How to make anhydrous ethanol (100% alcohol)
Вставка
- Опубліковано 20 жов 2015
- In this video we will be making some 100% Ethanol from 95% Ethanol. I use molecular sieves but other drying agents can be used. I just like sieves the most.
I am in the process of making a patreon account for donations. I am slow so the page is only partially done. Several people requested that a make one. I'll add rewards and stuff later because I'm honestly not sure what to put there yet.

Nile talks about lab safety: • Chemistry is dangerous. - Наука та технологія
Also known in labs as "the good stuff".
Absolutely right! 👍👌
Omg, totally, haha! I have fond memories of my lab ethanol and diet coke days.
@@abhishaiyasonaimuthu9131 Me and my lab partners certainly did, haha!
@@abhishaiyasonaimuthu9131 pretty common actually. My partners and I have a set of very small breakers that are only used for consumption. We would never use them otherwise because they are too small to be useful for us. Anyway, we keep absolute ethanol that has no bittering agents in hand for various extractions. When we've had a good day, we all take a shot.

When I was in highschool I was in a chemistry club. I joined due to a girl I liked. Chemistry was fun and obv. I still love it, but my work is unrelated to the field. One time we had the task to ferment some grapes into a sort of wine then seperate the alcohol and later further destill it into 100% ethanol. This was a whole semester wide project that took many sessions time and effort on the whole club (6 people incl. the teacher). I remember very clearly when we had the 100% ethanol and how happy we were to achieve our goal. I remember filtering the ethanol with the m. sieves through a coffee filter. I remember washing the sieves with distilled water. I remember realising that I just dilluted the batch to less then 50% and so destroyed two weeks of work. That day I realized that I am just slightly, but definitively a moron.
do americans not use vacuum filters or what?
You tried and learned...
Don't call yourself a moron...
You never make such a mistake again...
Its just a learning process..
Its good you saw your mistake but don't ever say you are a moron... 😉
Should have realized you’re a moron if you were willing to join a club just because of a girl
Man you did cool stuff in class. We just had a teacher explain chemistry as dry as if it was math
That is some fun experiment.
At my school safety was not taken that seriously though.
We did the carbylamine reaction once, and produced a lot of isocyanide.
Had to stay out of the lab for a whole day after that, but it was fun.
I’m so glad I found this! I’ve been needing to make 100% ethanol as well for no reason. I don’t have any of the equipment or the money to buy any of the ingredients, including the ethanol, but it’s good to have the instructions on hand just in case.
You ever get around to it l? Can I borrow 5 dollars yet?
A bottle of Everclear is ~$20.
@@toughenupfluffy7294I'm pretty sure everclear is 95% which is the percentage nigel starts at
Any luck??
What about now?
Take a shot of ethanol every time he says "sieves"
Also for "molecular". ;D
Thank you for your suggestion.
Also unrelated but you got any spare liver someone could borrow?

My pharmacy sells 95% alcohol... [Laughs in Polish where literally every corner shop sells 95% alcohol]
As a Polish I drank 95% spirit one too many times 😂 I burnt my oesophagus and now I have stomach ulcers 😅
@Dennis Young What's shellac?
@Dennis Young Nah, the reason for having 95% alcohol in almost every store is definitely not shellac.
Personally, I use it for this:

Fun fact, undergraduate labs sometimes include additives that make anyone who would attempt to ingest the alcohol puke it up faster than they would with actual alcohol, so at the undergrad level it wouldn't necessarily be 100% anyway, azeotrope or no azeotrope.
At least that's what they tell the undergrads...
100% ethanol is poisonous.
@@mattmoy2000 Feed some to the class mascot gerbil, observe the results.
Fun fact, you can get drunk off most alcohols. Propanol, butanol, isopropyl, you name it. Moreover, as the number of carbons increases, the more intense the drunk feeling is. 1 ounce of isopropyl could have you floored in 30-60 minutes. Then of course there is methanol which metabolizes to formate and destroys the optic nerve among other things.

I drank a pint a day for a year
But because i was broke and it was the strongest cheapest liquor
If i could afford 4 pints of jin a day that would be way less harmful

Another of your experiments that I cant wait to try! Thanks for always providing great projects and fun things we can try at home with just a little bit of effort! My clear wood continues to impress people and I intend to try it again soon. Thanks again, NileRed!
You missed some ethanol at the filter. Try washing it with a bit of distilled water!
LOL

thanks for the advice bro
Lol there is a story in the comments of dude doing exactly this in his high school chemistry class and realizing just how much he fucked up
Chemical engineer here. First of all, great clear and quick explanation of azeotropic distillation even though you opted not to use that method. I rarely, if ever, see it explained so clearly in my engineering books.
A couple things worth noting:
1) Mole sieves are the pretty much the best nonreactive way to get contaminants to the lowest possible percentages if they're applicable to the situation. 3A is perfect for removing water as it doesn't fit almost any other molecules except H2O into the pores. However, mole sieves have much lower capacities in exchange for their high adsorptivity. 5% water is probably too much for a mole sieve I thought up front, but I was pleasantly surprised that you were able to adsorb all that water in just two treatments. At higher volumes, though, mole sieves would become uneconomical. Great for keeping your ethanol dry, though, in storage as you're doing.
In engineering practice at larger volumes, using only adsorption, it's most cost effective to use alumina first as a cheaper bulk adsorbent for water, then polish the last remaining bits of water out with mole sieves. Both can be regenerated with heat. Silica gel is another possible adsorbent that can be regenerated, but you'd have to check your gel's affinity for water over ethanol just to be sure it'll work. Adsorption is a very versatile separation method as long you do your adsorbent homework.
2) There are a lot of other ways of "breaking" azeotropes listed in the Wikipedia "Azeotrope" article. Changing the distillation pressure will usually change the azeotropic temperature and composition allowing you to get past the atmospheric azeotrope. Apparently, that pressure swing effect won't work for ethanol-water, but it's viable for other mixtures. Using selective membranes will also work. There are many other methods. Obviously, not all will work for all types of mixtures or be viable at lab scale. I just wanted to expand upon your point of showing that there are a lot of other interesting separation processes, both physical and chemical, that we use after good ole distillation reaches its limits.
modified Corn grits are used in industry to dry 50% of ethanol in the midwest usa. like 3a sieves, they are regenerated in the column, and are reused for many cycles.
I'm not so sure if any denaturants will be left over during distillation... at least in the US they use additives such as Pyridine, and Methanol to make it poisonous, Denatonium Benzoate as a bitterant, and sometimes even a bit of acetone makes it in there (mostly in Isopropyl rubbing alcohol). The addition of Toluene to form an azeotrope to decrease the distillation temperate is interesting. I'm just wondering if any of the Toluene might escape into the distillate, therefore fractional distillation might be necessary. By the way, denaturants are added to prevent drinking it, AND to collect tax on drinkable ethanol.
Great, now the word "adsorb" looks weird.
Chemical engineering is fascinating
What's alumina?
Always diverse...always interesting! I wish you teach other yt'ers your methods of work, presentation and enough pertinent information as instructions and safety precautions to make each video unique and a pleasure to watch!
Thank you for sharing, yet again!#!
Thank you for the video. Something I have had to explain myself and you did a good job. I worked at a chemical plant. We ran a reaction with 99.5% ethanol. We bought the ethanol in rail car quantities. Water would react in the place of ethanol as you mentioned. Other alcohols would also react in place of the ethanol so we could not use ethanol denatured with other alcohols. Our ethanol was denatured with toluene which was inert in our process and was stripped off later in the process.
Just a note, a lot of ethanol is denatured by a mix of methanol and isopropyl alcohol about 0.5% each. A small fore cut on your distillation removes the methanol but, by distilling to dryness you left the isopropyl in the ethanol. You would probably need a good still with a reflux column to really get all the other alcohols out.
2019: Let's use the alcohol to make moonshine

Let's use the hand sanitizer to make moonshine
_roman420 that one dumbass who hoarded thousands of hand sanitizer to resell on amazon but rejected can do that for sure
how do y’all even understand this i am so confused
Snarky . Live they seized his hand sanitizer? That’s beyond satisfying
I know this was a joke but you actually don't want to go above 60% for hand sanitizer, >60% is less effective.
How nerds make moonshine...
+magicstix0r At 100% that isn't moonshine. That's liquid fire.
+steven spall would you be able to drink that
Technically yes. Ever clear is 95% and it has a warning that says not to drink it straight, but I've seen people so it anyway. Personally I can't handle it. It burns to much. But if you can handle the burn, yeah.
I'll give an actual answer two years later. One major thing they add to ethanol to keep you from drinking it is methanol, and while it is possible to remove methanol, he didn't take the necessary steps to do that, so this probably wouldn't be safe for drinking.
WindowHero and another point added 2 years and 6 days later, drinking 100% ethanol is very dangerous. Your typical bar hop 6-7 shots would probably land you in a hospital unless you have some God like tolerance. Your typical shot would only hold 35-40 %. So, using as little math as possible, 1 shot 100% is roughly the same potency as 3 shots of Grey Goose.
You're a life saver! Had some 3A sieve hanging around, glad I didn't toss it. Thanks :)
Another possible drying agent is common table salt NaCl as it is hydrophilic and insoluble in alcohol. The salt combines with the water but remains insoluble to the alcohol. This causes the alcohol and water to separate into two layers with the much less dense alcohol floating atop the denser salt water. The alcohol can then simply be decanted off leaving the salt water behind. One could also distill the alcohol off the salt water as well, but that would be more time consuming and more effort.
The remaining saltwater can then be dried which will leave your salt behind able to be reused again in much the same fashion as your filter beads.
Molecular sieve dust can interfere with reactions, and the sieves do effectively gobble up a good chunk of your solvent (as you can't fully drain the flask).
If you're going to distill the ethanol anyway, there is a better route that does remove ALL the water (down to undetectable levels - sieves can't quite get there and a small amount of water will be released towards the end of the distillation if you end up distilling it dry).
Put your azeotropic ethanol (or sieve-dried ethanol!) into a beaker, add a lump of sodium (sufficient to react with the water present), wait for it to dissolve, and then distill the resulting mixture. The sodium lump will immobilise the water into sodium hydroxide, allowing you to distill the solvent mixture to dryness (don't do this at a large scale, as dangerous contaminants may collect - but for lab scale there's no issue). Excess sodium will form sodium ethoxide, which is a water scavenger itself (it reacts with water to generate ethanol and sodium hydroxide).
If you want to do this process at large scale (check local law!), you want the benzene pressure-swing process.
It's not regeneratable but it will give you analytically pure ethanol. You can store it over some magnesium turnings, which can be used in the place of the sodium if you like - although this route needs a crystal of iodine to activate the magnesium [breaks through the oxide layer] before you start. So really it depends on how well-stocked your lab is!
You're cool I love you
Thanks Walt
Okay Mr White
yeah mister white! yeah, science, bitch!
Based chemist
I really love your experiments!! I just wanted to share some things I’ve learned about sieves. Molecular sieves will slowly pull air molecules into their pores as they sit. It is generally best to freshly bake the sieves before using them. This drives the gases out of the pores and allows the water molecules to be literally pulled directly into them. It’s essentially a vacuum that adds a lot of extra pull. You can demonstrate this by sealing freshly baked sieves in a plastic container, and as the air is absorbed, the plastic container will collapse.
If you don’t use freshly regenerated sieves, you have to wait for the air molecules to get driven out (displaced), which adds a significant amount of time to the solvent drying process.
Thank You, I did not know that! Makes sense.
Take a box of corn starch spread it on a cookie sheet. Place in a 250F oven for a couple of hours to dry it from 11% w/w moisture to 3-4% w/w moisture. Place it in a glass container with a silicone snap lid until ready to use. When ready, dump it into the 190 proof ethanol and stir for a few minutes. Filter the corn starch out on a coffee filter and your ethanol will be 199 proof. The corn starch can be recycled by letting the ethanol air evaporate and redrying the starch in the oven. Be very careful with the re-dried cornstarch as it's explosive is dispersed in air. Your 190 proof should be booze alcohol because the starch won't necessarily take out denaturants.

Use cotton wool to filter stuff. Thats what we use for HPLC and LCMS at our company. Pretty much all colloidical residue remains at the filtering agent.
I was freaked out when you put the foil over the vertical tube and y adapter. DON'T YOU NEED TO MEASURE THE BOILING POINT?? But then I realized there's not actually any water left to recondense in the collection flask. Nice procedure, Nile.
There is a hybrid distillation technique using glycerol.
Pass the ethanol vapors through hot glycerol; the ethanol passes right on by, the water hangs out to party!!
Glycerol is easily swapped out & dried.
Nice idea. I'll have to try that.
Reminds me of purifying hydrogen gas with Pd.
Man the shit I learn on youtube... really makes me regret not taking chemistry education
Wow so you could add this as a part of your moonshine set up?
Like into a second thumper?
Not 100% but will get more than 95%.
There is a third method as well, which is pressure swing distillation. After reaching 95%, take that mixture and do a high pressure (10 bar) distillation, and the ethanol will come off the top at nearly 100%.
Random algorithm recommendation... interesting to see the origin story of NileRed.
In power electronics assembly with solder strips instead of paste we use a small of 100% ethanol between the chip and solder to hold everything together. In the soldering oven the ethanol evaporates away without effecting the soldering surfaces

An excellent video. More than 40 years ago I used to share a lab with someone who regularly had to produce 100% ethanol so that he could make a metallic compound that was very sensitive to water, also air. He used the magnesium method, and used to say that it was one of the more difficult experimental manipulations he had to do in obtaining his PhD. Grignard reagents are of course one of the standard ways of alkylating anything, particularly if you can't buy pure alkyl lithiums.
Excellent tutorial. You're a natural teacher. Keep going.
Hi, Pixel Schnitzel here. I came back here from the future to tell you that this is, by far, a better format than you'll be using in 2023/24. Please consider keeping it like this.

Nile Red: I'll do this extra step and distill this to get rid of the sieve dust.
Also Nile Red: Since we removed the sieve dust I'm going to pour it back into the ethanol.
best chemistry channel i've seen. Good work. You earned a Sub.
By far one of the most useful of your video, since anhydrous ethanol is difficult to find and quite expensive!
Thank you Nile, now I know how to make every hour happy hour, gonna whip some up tomorrow
Fun fact: in Poland you don't have to go to pharmacy to can get 95% ethanol - you can buy it in most grocery stores. We use them to make a liquor called "nalewka" that's prepared by pouring it over some fruits or whatever (I like to dump some anise into the spirit) and leave it for a month or so. In case of the watery addon it usually makes the concentration go down to 40-60% which is perfectly drinkable.
It's important to note that when you remove the H2O from the ethanol, in order to keep it at 100% ethanol, you should keep it in an inert atmosphere so the water vapor in the air won't diffuse into the ethanol.
Thats why he added the sieves in the bottle again, so if the concentration ethanol went down they would absorb the water again and the conc would go back to 100%
Yes, because ethanol is hygroscopic.
Im so dumb. I just looked up the definition of 'anhydrous' lol i probably could have figured it out had i thought about it for 2 seconds.. You're a huge inspiration NileRed!! I did my first acid to base extraction the other day! You trained me well!

Thanks nilered! i will use this to disinfect my throat and stomach!
Molecular sieves (like zeolite) are also used in medical and industrial oxygen concentrators. Remember that atmospheric air has only 21% oxygen. Molecular sieves allow oxygen molecules to pass but leaves the other gases behind, so it makes 30% - 99% oxygen from room air.
You are an excellent chemist. Much respect to you from a junior chem student.
Nice work,I got it, thanks for information
Thanks for your content.
Molecular sieves are a comparatively recent development. Back when I was in school, we used calcium oxide (quicklime). CaO + H2O yields Ca(OH)2.
where yields confirmed using hydro-meter?
I would've went with sodium
@@olegshevchenko5869 No good, as metallic sodium reacts with an alcohol to produce hydrogen gas and sodium alkoxide. Alkoxides are useful nucleophilic reagents.
@@eliduttman315 That's not much of an issue, though - sodium reacts with the remaining water to form sodium hydroxide, and while it does indeed form sodium ethoxide with ethanol, the equilibrium favors the deprotonation of the stronger acid, which in this case would be H2O. Thus, if you only add a modest excess of sodium to your azeotrope, you can easily separate the anhydrous ethanol from the newly-formed sodium salts.
Magnesium sulphate was what we used
Finally. The perfect drink to have during the debate tonight.
Chris Wallace also ordered one shot during that "quarrel" @ Bad Lip Reading
Ahh, politics. No matter how much alcohol you drink, you're still too sober to enjoy it
Trying to make Mercury Fulminate by using Absolute Ethanol, this video helped a lot, thank you sir!
I add dry magnesium sulfate to the 95% etOH then distill it from that. The MgSO4 helps it boil. Some molecular sieves are added to the receiver to grab what's left.
I did this last year and before I added the sieves I destiled the alcohol, the reason why is because denaturing agents are a type of soaps and the sieves once dried in the oven can be less efficient next time because they have this agents in the surface. So, first a distillation to remove denaturing agent, then sieves, and after a second distillation to clean alcohol from dust. Good sieves are not cheap but alcohol yes, so I prefer take care of the sieves.

Thanks 👍🏻 good tips
this was awessssoommeee!!
BTW - another use for 100% ethanol is for quick test of circuit boards for shorts. Can't have any water in it when pouring it on; or you are making a short. Since a short creates some heat, the alcohol will evaporate quickly and leave a dry spot - which is easily noticed. However, if the short is too hot it can be a catastrophe by making a fire. Best used for low amperage/voltage (less than 100mA) short detection using only a small amount of alcohol and checking only a different small area each time with good ventilation . . . Use utmost care - you are responsible!
Pure water is actually a pretty good insulator.
Bro you have an amazing channel. Been watching tons of your vids.
I’m feel like a chemist just watching you lol!
Details @ 1:47, the audio says that "ethanol" is poured into the graduated cylinder whereas the closed caption states that it is "methanol". Furthermore the label on the bottle states that it contains 95% ethanol.
It’s wild to see Nile from 6 years ago. So much is different.
Here's a tip if you want your ethanol really extra sooper dry : dissolve a little bit of sodium in it prior to distillation. Of course, this only makes sense if you then handle it in a dry atmosphere (for instance, via a Schlenk line), or it will otherwise pump moisture back from the air. (but if you have a schlenk line, distillation becomes super easy : you don't even need a condenser! Two flasks, a T-shaped piece of glassware and some liquid nitrogen are enough!)
I used to distill solvents (including ethanol) over the sodium mirror to remove water to approx 10E-5%. Basically, a metal sodium is evaporated in the distilling column and solvent vapors are passed over bare metal, eating out all water molecules. Of course, everything is done under vacuum and purged with nitrogen or argon.
For those who can afford, a metal sodium can be replaced with eutectic mixture of sodium and potassium, forming liquid alloy, which can be stirred inside the flask. A sodium itself is quickly getting covered by hydroxide, slowing the process.
100% ethanol is really important for certain molecular biology procedures like DNA extraction and purification. This is a good procedure to know, thank you.
At the end when he said to store the ethanol somewhere safe, I really hoped he would also add 'do not drink' cautionary.
I was in the petroleum service industry from 1998-2012. I remember years before then hearing about the difficulties of producing and storing what they called gasohol. Later, when my job was addressing issues caused by water contamination in 10% ethanol/ gasoline blends, there were many solutions, however, few of them were practical and none of them were long-term. Needless to say, it was a constant concern. There were so-called water filters that were made for alcohol-blended gasoline, If I'm not mistaken they used corn starch to absorb the water, and clogged quickly.
I love your glassware, Nile.
you can mix it with Aluminium ethanolate. It will react with water to form Aluminium Hydroxide and ethanol
I grew up on a farm and we had neighbors that had a large ethanol still that they were experimenting for use as fuel. (I’m not sure if that operation was legal). They tried mixing it with gasoline, it separated and they didn’t know why. This was in the 90s before the internet was useful for that sort of question. I was recently thinking about that and 30 years later I went down that rabbit hole. I figured out the water issue from written material online but the Google gods decided I needed to see this video too. This time they were right because reading about how that works at industrial plant is one thing but seeing what it looks like on a small scale is interesting.
That was educational!
When storing the 100% ethanol in the bottle it occurred to me that you could put the seeds in a paper teapouch to keep the dust from getting into the ethanol.
nope, not small enough as shown in the video when the coffee filter was used to try and get the dust out
As well as commercial molecular sieves you can use cement powder and starch, both of which adsorb water, but not alcohol. As with the commercial molecular sieves a second distillation would be best. The added advantage of these is that they're much cheaper and more readily available. Would you consider doing a video to try out these methods, just to compare? Thanks for a great video!!
the days when nilered was in a garage i trust this more than any other video still
Thank you. Very delicious.
There is also the option of distilling under a vacuum. However, making ethanol that is about 100% is pointless as it is hygroscopic and will attract moisture from the ambient as soon as it is taken outside the vacuum conditions.
By the way, it's a great solvent for making plant-based potions because it evaporates easily and is not poisonous in trace amounts. 100% is good if you're making oils for instance
Yep, my reason for watching this vid. I got mad just to be able to buy 95% ethanol :S
I saw a doc. on Jonny Appleseed. He in fact planted apple trees to make applejack. In the winter people would put their applejack out side. The water part would freeze but not the alcohol part. Pick out the ice and have stronger liquor.
Where did you get your drying agent from. Great information and sure makes things easier.
You didn't put the ethanol back into the original container because it had some left over denaturing agents!
Ha-ha I realized as I was making it that someone would comment :p. I wouldn't cleaned the bottle first. I just like glass bottles though. Makes me seem more pro

Now it makes sense why Brazilian ethanol at the fuel pump is around 96%, great video
In the pre molecular sieve days, they poured the alcohol through wheat straw, to get 100%.
Pretty much the same principle as molecular sieves.
Do you have a video about Bio-diesel, a demonstration or description on how to process or a good reference? Your videos brought me memories of my Chem. Lab. days in college. Thank you.
you can also do a pressure swing distillation... but that is for industrial use :D
Weekends gonna be liiiiittt fam 🔥
I have been wondering if you could not get rid of the dust by washing them sieves beforehand, or do they constantly decompose?
Mine produce substantially less dust after being washed, maybe there will be none after more washing. The dust should be active though as the adsorbtion happens on the molecular level.
Libor Tinka does its effectiveness diminish per gram over the life of the sieve, regeneration after regeneration?
@@EdIvory I used to use molecular sieve to keep an FTIR spectrometer free of moisture, and over time it does seem to lose its potency. We had to order more every so often. I don't know the particulars of by how much over time, but for us, it was about 2-3 years of use it kind of lost its potency to the point you had to toss it and get new sieve. That may have had more to do with what we had to recover it (a simple toaster oven without a fan) than the sieve itself. But I did bake it at the temperature and for the time the label on the sieve said to. If I had to guess, I'd say other contaminants eventually build up within or on the sieve over time so that it cannot adsorb enough water to be wholly effective.
As far as dust goes, I never washed sieve, but dust was always present, no matter how much dust was left behind in the oven I used to recover it. The sieve is basically a type of hard clay, so it is brittle. It just seems to create more dust over time.
@@EdIvory I haven't used it in so many cycles to notice but maybe crushing them would increase fresh surface area and make the sieves live longer. The 3A sieves can be obtained cheaply but high quality zeolites are expensive.
I have firsthand experience with this. A wash certainly helps, but is not a perfect solution generally. The dust is extremely fine and can be difficult to filter out.
In a batch configuration like in the video, you basically have to do a distillation to get the inevitable dust away.
I can tell who's a chemist in the comments and who's not based on the whether they mention getting drunk or not
joseph jackson Chemists drink too
I'll puke on your shoes to that
You got be one hell of a brokedick peckerwood to think chemists and get crunk better than everyone else.
I feel like I’m gonna get put on a list for watching these videos 😂
Interesting, thank you
