- In this video, we make some acrolein by catalytically decomposing glycerol.
This video had to be made outside, so the lighting is not the greatest.

Nile talks about lab safety: • Chemistry is dangerous.
"I really don't ever want to work with it again," coming from the guy who makes Chromyl Chloride for fun, must be no joke.
It was a wwi chemical weapon
That says a lot
And apparently people who smoke are constantly exposed to this shit and expose others to this shit
Toxic and carcinogenic is fun, but stinky isnt
@@DarmaniLink your welcome
Guys, when it says: "altered gene expression" and "mutation", read: cancer and tumours, not x-men abilities, though. lol
You cant drink everything that looks like soda i hope you know.
It taste like burning.
Speak for yourself, I for one am expecting my wolverine claws any day now.
That still doesn't explain where my fourth testicle came from.

This is honestly my favourite channel on youtube, so satisfying to watch the whole process
Thanks, I appreciate the comment!
Agreed

So is this like cancer sauce?
lol exactly
cancer sauce is benzene or chromyl chloride
More like a cancer demi gloss.

Acrelien is extremely irritating! When things burn they only make traces of it.
Oh cool, a new episode of Edible Chem !
The forbidden edible chem
Yummy
I could go for some good ol' acrolein right about now. Maybe with a side of chromyl chloride.
@@annacochran4418 mix em together and drink from some uranium glass :)
everything is edible at least once
Acrolein is brutal even with a fume hood. You've got balls. I've also had polymerization destroy reagent bottles.
Yeah, it definitely was not nice. Also, polymerization is so unfortunate.
AX gas filter should work for this substance, but only for a limited period of time (depending on ppm concentration, max. single "shift")
Acroline is really nasty stuff. I used to do research on renewable diesel made from various vegetable oils. Even with a fume hood, one whiff and your head is spinning.
ever figure out which vegetable oil was the best for engines or was the project abandoned?
Also wondering did y'all ever publish?
@@starlitstreet if i remember correctly, every vegetable oil produce the same biodiesel (with different proportion) and it's more of which one is efficient conversion (biomass to biodiesel conversion rate as well as which one require less material/energy to do).
@balddicknosedasscanoe i don't know, i am just a student and one of the topic i need to review just focused on conversion rate and finding parameter that matter and how it affect it. While surfing through, either i forgot that it have been mentioned or it rarely ever be mentioned is how the proportion (or rather different vegetable oil) affect the actual quality of the biodiesel when it's used on the car.
(My guess is that, just like many other production. You just compensate the pure biodiesel created by mixing it up with other chemical or treated in order to reach desired value. So... No idea for the home-made one. Or it's separated topic that are scrutinized independently of each other which i highly doubt).
@balddicknosedasscanoe um, just a little question just to make sure we're on the same page. When you said biodiesel, do you just mean vegetable oil or an alkyl esters which is biomass (including vegetable oil) that already went into conversion into biodiesel.
I am really sorry for this as i have a feeling that we're not actually talking on the same page....
This was my fist experiment for practical organic chemistry. Needless to say that we were very happy that we had decent fume hoods.
NileRed: It's extremely dangerous, and should be handled with care
Smokers: We're all dying anyways, so let me just~
might as well not cook your food anymore as well
The doses are what’s bad. We all know cigarettes are worse than cooking your food. Inhaling smoke is worse. There’s still only traces left behind from both reactions. You can’t judge anyone honestly whose addicted unless you’ve personally experienced it.
@@nebulousisgod I’ve never done meth before and I can safely assume those addicted to it will be incredibly unpredictable and undesirable
@@elijahaitaok8624 uh huh. You can also just ignore the circumstances that brought them to it, but whatever.
@@elijahaitaok8624 funny enough buddy, I’ve found a lot of junkies that are better people than a lot of straight edge mfers, they would give someone the shirt off their back, don’t automatically assume they are undesirable and unpredictable, the unpredictableness comes from psychosis which is really no fun, as long as they sleep then it’s a functional substance, even with how addictive it is, you also have to think about the bioavailability of the different Routes of Administration, which offers the most intense rush, orally it’s not too far off from adderall just more potent, but iv’d, intranasal and boofing are what really fucks it up and causes the euphoria to take complete control, if you think everyone of them is so down bad and so under control that they are willing to stab you for a shard, then your wrong man
I understood about 5% of this video, but it's still fascinating to me how complex chemistry actually is.
Every time I’m stressed or sad I watch this video... I don’t know why, I just do! Thanks Nile!
You know this dude has to have the gnarliest bong you’ve ever seen.
Hell yea
Chemestry videos in 60fps look so amazing! Thank you nile!
uh...but it’s not 60fps...?
@@ARSZLB it is
In my entire school life we were never taken to chemistry lab for practicals . But becz of your channel I got satisfied. So thanks alot
I'm glad you made this video. I have done acrolein twice. In my first synthesis I used a dropping funnel just like you and I found it completly unnecessary as well. I did't use the second flask with sodium chloride and i just took the receiving flask and used a vigreux columnfor second distillation. I also used potassium bisulfate instead of magnesium sulfate. In my first time my yield was just 17%, so next time I used twice more potassium bisulfate and that incrised my yield to 31%. I stored my acrolein in freezer but a week latter I also had just polymers.
yeah and i believe that the best way how to clean the boiling flask is just pouring solution of sodium hydroxide in it and let if react for day or two, than the flask was completly clean. :)
Explanations on cleaning chemistry equipment are always welcome, you should make a series on that topic.
Lots and lots of potassium hydroxide, water, and ethanol lol.
Next make Sarin.
9:33 Nile, Patrick needs his lab jack back.
What if I am Patrick?? (I am not though)
NileRed Did you take Spongebob's lab jack, too?
i just figured the jack was named patrick
i knew i wasn't the only one who noticed that lol
@@NileRed who is Patrick tho...
one of life's deep questions
I'm super glad I watched this, at first I was like 'meh acrolein' but this actually helped me identify the terrible, terrible smelling stuff I produced when I left a flask on the heating mantle to distill and forgot until the next morning. Also, I think I'll be making up some piranha solution now, and maybe I can actually use the flask again!
It makes me wonder if this is what I produced when I left caramel cooking on the stove for something like 5 minutes too long while I completely zoned out in something else. I came back into the room and it was filled with this incredible, acrid stench, while my caramel saucepan had turned into an evil-looking black boiling cauldron. I was supposed to have let it cook for perhaps 15-30 seconds, so five minutes was an eternity.
@@jeremymozlin just burnt caramel lol but idk if it could be acrolein
@@jeremymozlin if you’re caramel was glycerol then maybe?
Who is Patrick? I saw the name on the lab jack.
The jack's name is Patrick
Yes, this is Patrick?
"It's just a horrible thing to work with"
Just like my ex wife, burns my eyes and smells like tobacco, irritates my nasal and respiratory tract.
HAHAHAHAHAH
funniest thing I've seen all day 😂😂
haha
She still smokes?
All too true, but you really should have reconsidered writing your own vows.
Acrolein (systematic name: propenal) is the simplest unsaturated aldehyde. It is a colorless liquid with a piercing, acrid smell. The smell of burnt fat (as when cooking oil is heated to its smoke point) is caused by glycerol in the burning fat breaking down into acrolein. It is produced industrially from propylene and mainly used as a biocide and a building block to other chemical compounds, such as the amino acid methionine.
One reaction that I think you could demonstrate would be the transesterification of vegetable oil with ethanol or methanol. You could then e.g. also demonstrate the difference in viscosity between the oil and the products.
From my lab experience, a mixture of crushed ice and scouring powder is a very good and completely safe way to get rid of all sorts of solid remains in reaction flasks. Just put both of them in there, close up the holes and give it a good shake.
Seems like I've learned my lesson. Cover opponents monsters in aluminum foil to break fusion decks.
I love watching these because it gives me the satisfaction of knowing that this is really cool, but I will never know what any of this actually means
Some old literature sources claim that if you use KHSO4 instead of MgSO4, the reaction takes place at room temperature
Acrolein: Used in cigarettes AND tear gas
Soldier who smokes: Joke’s on you, I’m into that
He got da tolerance 😎
Hey! You forgot the links in the description at 2:15.
Your videos are awesome by the way. I'm going to be starting my senior year as a chemistry major and it's always exciting to see you come out with a new video!
If you don't mind me asking, are you a graduate student or do you just enjoy chemistry as a hobby?
I did 6 months are a grad student but left for some personal reasons. Right now I guess it is technically just a hobby. Good call on the links
Chemistry is crazy interesting but at the same time very scary. I learn about this stuff theoretically but seeing it actually take place is surreal
Apparently there’s acrolene in the atmospher of jupiter or somewhere out there
Look at that perfect 60k, congrats, great work
Thanks!
Watching with my roommate when he asks what the difference between “HO” and “OH” is.. I quickly reply “a whole argument and a man realizing he’s wrong…”😅
Look at the lab jack on the second distillation (9:36), it has the name "Patrick" written on it.
Nile Red = Patrick??????
No, he mentioned before that the name NileRed comes from the first letter of his name, "N"
Npatrick???
Hm....HMMMMMM
HMMMMMMMMMMMM
He looks like a Nathan to me honestly
No, no. Looks like Niels.
I love the explanations of how the molecules are changing. The hydrogen is kicked off, swings back around, grabs an Uber, drops off his dry cleaning and joins up with the hydroxide for an after-party.
Great video! shame you lost your product :/ could that have been avoided by adding more hydroquinone? also, looking forward to your bug attractant video, I'm sure you'll do a great job with that :)
What is acrolein found in?
Acrolein is formed when fats are overheated. Small amounts of acrolein may also be found in foods such as fried foods, cooking oils, and roasted coffee.
He’s putting that warning there as if I’m going to go all Walter White and make some myself
Do some beautiful Diazonium chemistry. Maybe a fluorescent dye.
BTW, hydroquinone might not be the best choice to stabilise acrolein as it is a quite a bit nucleophilic. I think you might have gotten an anionic polymerisation.
Ha, I just had a project in process simulations to make an aspen model to turn polypropylene into acrylic acid with acrolein as an intermediate and got recommended this video
Don’t really understand ANYTHING in this video but it was cool to watch and learn a little bit about it
this makes me want to quit smoking
Really interesting reaction.
just a suggestion. All time we work with HNO3 and produce NO2/N2O4, is a waste of Nitric Acid, since is possible to condensate and mix nitrogen oxide with water and make more Nitric Acid, reducing losses.
Would be interesting a video showing NO2/N2O4 recovery and liquefying it, like you did with NH3. Also, you can explore and show the hypergolic reaction with Aniline or furfuryl alcohol. :)
I'm surprised you made something as potent as acrolien. That's wicked stiff. I wonder though if it would keep as a bisulfite complex.
You didn't provide links in the description :(
Would be amazing if you could synthesise some pigments like pthalocyanine blue, quinacridone magenta or some of the cadmium colours
As soon as he said "polymerization" I knew piranha salutation was going to be used.... Apparently I learned something, IDK what but I learned something.
Who else watches because it's interesting and not because they are doing it themselves?
we all do
yea, we are all smart. lol
Bakedpotato2468 I today just watch for fun.he has some super funny moments
not me XD
Yup.... I've no fucking idea what any of it means 🤣🤣🤣
Pesky acrolein, always polymerizing when you don't look at it!
Thanks so much for the cleaning section... so important!
If you see closely at the middle flask and the other flask you can see his face lol
I had troubles hiding in this one
I don't know jack about chemistry or science in general, but man your videos are awesome. They really hold my attention.
Could you do a video where you separate aspartame into phenylalanine and methanol?
I think i looked into it and it wasnt super easy to do. Maybe I could make aspartame though.
Aspartame is pretty hard to make from the research i have done. It involves culturing these 2 bacteria species, collecting their waste, and then fermenting them together. Nasty stuff.
"It also smells bad" LIKE THAT'S THE MAIN CONCERN!?
make a video on menthol
Acrolein sometimes forms in e-cigarettes when using one without liquid by mistake. The high heat without liquid to wick creates acrolein from the glycerin (or propylne glycol).
It is a horrible experience, burns the throat, the mouth. Once my e-cig malfunctioned and burned in my suitcase. Nothing bad happened but all my clothes smelled terrible. A burnt kind of smell that makes you gag.
Acolein is also use for Methonin production
8:18 There's been a contamination Jesse.
I'm not a chemist by any means, literally, but my time at a bakery taught me- ALWAYS add solids TO liquids, else the solid may form a small barrier on the inside of the container, and you wont be able to incorporate 100% off all ingredients at 100% efficency. Now as a question, does this principal apply to chemistry as well???
8:15 a bug wants to get mutated by acrolein
Finally, the 1 million mark👏👏👏
Wheres the link in the description of the tautomerisation mechanism ?
Oh I forgot
All good man :)
what kind of respirators do You normally use for some of your experiments
no ther is very easy methode we just destylate
sunflower oil with small amount of sulfonic or sulferic acid as a catalyst ....your brother from algeria
I'm glad you cover ww1 stuff
Somebody should invent a dishwasher that's using piranha solution instead of water
Handy Spülmittel bye bye metal dishes
What's with these avatars that make me think I have an eyelash on the screen?
Surprised I didn't hear: "At the end of the experiment I was still alive, so I figured there must have been something I did wrong."
did you ever try bleach and salt to clean the glassware? works nicely on burnt cookware.
Really? Ive never tried that. I guess it is a mild oxidizer.
The salt works as an abrasive, so you don't really need to fully oxidize the material, just loosen it up enough to be removed by the coarse swirling salt.
I have worked with this stuff in gallon quantities on pilot-plant scale research. The idea that anyone would want to actually make it is mind-boggling. The worst thing about it is the effect on the eyes. First, your nose starts to twitch then in about 10 seconds your eyes become seriously painful. This, apparently, takes about 5-10 ppm. The only solution is to calmly walk outside into the fresh air. Eventually you'll be able to open your eyes again. BTW we pronounced it with the stress on the first syllable thus AK-ra-lin.
At last acrolein thanks mam. Luv u bro

I noticed the fly and now I can't see anything but the fly buzzing around the background.
I still don't understand why I recommend this UA-cam
Respirators dont stop it huh? Alright ATF agent, your move
NileRed: This is probably one of the worst things I have worked with
Me, knowing he made uranium glass: Hmmmmmmmmm
A very good way to clean the whole setup is Nitric acid. Just destill it threw there (no cooling) and everything will be super clean again.
Leo Curious nitric acid is valuable...
Add some clean sand to the flask when you wash it and shake it with the stoppers on. Probably not advisable to do this when using strong acids though...
Acro-lean like da bouncy sizzurp
When he put the “addition funnel” in it looked like a bong
This randomly showed up in my recommended, cool ^^
if this guy went full walter white that shit would be so good.
Years old video, but figured it would be worth a shot.
Would it be possible to react acrolein with DNA from something like strawberries?
yes, why wouldnt it be? DNA is DNA
Most reacent comment was 3hours ago, this video was posted 5YEARS ago. I also just got reccomended this
I could hear the hatred in his voice throughout this video
+NileRed By the way, how would you describe the smell of acrolein?
Acrid, and very sharp and terribly irritating to the eyes and mucous membranes.
Use some bear spray as deodorant with a sprinkle of rotten eggs
HUGE fan of your channel, but maybe make the warning about possible death longer than half a second
Acrolean 😏
That’s a funky lookin bong
“It looks like Atari mess.”
@13:36 I had to laugh at that spider photobombing your shot!
I wrote a comment previously but I had to cover it up with aluminium to prevent polymerisation.
my older comment still hot polymerised
what is the reason for the aluminum foil? Love your videos by the way :) want to go into organic synthesis and these really pique my interest
UnKnOwNzzz acrolein is light sensitive. If you don’t protect it from light it will rapidly polymerize
That feeling when you don't want to make more Acrolein so you use Formaldehyde instead
Last time I was this early, this joke was funny.
Oh hello random UA-cam recommendation that I watched all of.
Is this the Jiffy-Jack?
No, this is Patrick.
It's not true that respirators can't stop acrolein, a full face respirator with an AXP3 rated filter is fully capable of that
