I've always found it interesting that you can make minor modifications to aromatic, fragrant compounds and completely change their aroma such as is done here.....even more interesting is the way that isomerism and particularly chirality can make huge changes as with chiral isomers of carvone which can either smell like spearmint or caraway depending on their L or D form.
My favorite example of the huge changes that come about due to isomerism is the racemates levomethorphan and dextromethorphan. Levomethorphan is a potent opiod, several times more potent than morphine. Dextromethorphan, though? No opiod activity, it’s actually the active ingredient in the over-the-counter cough syrup Robitussin. I think it’s quite incredible, honestly. The left-handed isomer could kill you with a couple dozen milligrams, and the right-handed one is sold every day for maybe 20 bucks per gram. Chemistry can be wild.
I recommend a survivalist series, an apocalypse simulation where you get useful chemicals from common goods we can find while scavenging houses. TEACH US HOW TO DEFEND AGAINST THE ZOMBIES!
-What a tedious synthesis! :D Extractions are my favorite workup procedure, though. Well done as always! And I admire how you explicitly covered the mechanism.
That 5 liter beaker made me laugh at the size of it when you picked it up. Didn't look that big in other shots and I wasn't thinking it would be that big
Injecting steam from an independent source would be best.Acetaldehyde will boil away and benzaldehyde is far more steam volatile than cinnamaldehyde.You also could reflux for 5-6 hours and keep the condenser water at 30Celsius(not the usual ice cold water) as acetaldehyde boils around 20C and will exit out of the condenser top! LeChatlier idea is by removing acetaldehyde you drive the reverse aldol reaction to make more benzaldehyde!
I don't know if you intend to be as humorous as you are but you have me cracking up through most of your videos. You have that kind of dry kind of witty humor that probably goes unnoticed by some people. I'm curious, what is the blue bottle experiment? And I would love to see a Q&A video, caffeine total synth, trimethylamine, and cyclohexanone oxime. So, I put my vote in for those next.
You could make benzaldehyde by toluene oxidation, or chlorination/hydrolysis. it gives the useful benzyl alcohol as a side product and some trichlorbenzene, which can be used for dehydration of compounds or be turned into benzoic acid to use as benzene precursor. Essentially turning toluene into 3 useful, less common chems in the lab
This gave me flashbacks to a chemistry class some 30 years ago. We were tasked with producing benzoic acid, and were divided into 6 lab groups. I don't recall what chemical was the starting point, but I do remember that the reaction involved boiling a solution, and that the chemical transitioned through benzaldehyde on its way to benzoic acid. So we were in a fairly small chemistry lab with six flasks of boiling benzaldehyde (almond essence), and well, let's just say the air got a little... dense. I don't think any of us craved marzipan for a while after that 😀
I think using a Dean-Stark trap for steam distillation is a better idea than distilling four liters of water. Why didn't you use distilled water from the receiver to replenish the level in the flask?
It's been a long time since I watched an old NileRed video. "I didn't use organic solvents to be environmentally friendly." from the man who makes his FAVORITE CARCINOGEN.
How much does all this distillation equipment cost? I have a lot of glassware, a butane burner, crucible, etc, but I'm thinking about buying a distillation setup. The only chemicals I really have is some semi-pure sodium acetate I made a few years ago, sodium bisulfate, acetone, and a few other things. I'm thinking about getting into more complex reactions since I understand safety, how to handle acids and very alkaline materials, and I know a bit about chemistry (although I am mainly a computer science person).
nurdrage has a link in his recent videos to a glassware supplier that has pricing info and there's also a discount code in the description hope that'll give you an idea about pricing, then there's always eBay but then you have to be careful to get the real deal
Thanks! I'm thinking about inorganic chemistry as a minor. I just love to explore chemical reactions. I'm majoring in Computer science though. Maybe I could make some cool apps to help with chemistry.
There are some apps that are quite good but others that just suck so do try them out and see if you can improve! A NMR and IR identification app would be awesome
I have one question because I have been clueless. I recently tried recrystallizing some KNO3 I bought online to try and grow some beautiful nitrate crystals, and after some time of boiling there was some left undissolved. I believe this was not KNO3 and had a much darker color like wet sand. I had originally tried dissolving it in smaller batches in a beaker, but it would start making this loud noise and shaking. I think it may be what is called "Bumping", but I've never heard anyone explain what it is except that boiling chips are used to prevent it. If you could I would really appreciate you opinion on the matter and just wanted to say keep up the amazing videos!
Bumping is caused by pockets of solution being superheated (above the boiling point) because there aren't enough bubble nucleation sites where the pocket is. Eventually a bubble will form and it will grow huge very quickly because of the high vapor pressure of the fluid being greater than atmospheric pressure pressing down on the solution. The bubble grows so quickly that it makes a mini explosion that often throws liquid out of the container. Boiling chips provide a surface with lots of irregularities so bubbles form all the time and they can grow before the solution gets superheated. That way they grow slowly, extract heat during the phase change from liquid to gas, and then rise to the surface gently and release the gas and the heat along with it.
Ashton Callender some potassium nitrate scores contain small amounts of sand as an I purity. I have performed that exact same expirement growing kno3 crystals. except I used stump remover and recrystalize it 1st, filtered it hot and let the crystals fall out. I did that with the whole batch. I then dried it out and stored it to use as needed to grow crystals and poor man's aqua reiga, etc. but that happens. I beleave it can be mined or made. depending on the score it may have slight contaminants.
reflux is just distillation without boiling something away? so, in essence, just the phase change from liquid-gas back to liquid produces the Benzaldehyde?
+NileRed Cool video! In the first step of the mechanism why does the hydroxide ion do a conjugate addition instead of attack the carbonyl directly? I though hard nucleophiles such as hydroxide prefer 1,2 over 1,4 additions.
What did the cinnamon oil smell like? Did it smell like cinnamon candy, or was it closer to cloves? Cinnamon leaf oil is actually mostly eugenol, and so if what you had was leaf oil, it would have had a strong clove aroma.
you should of steam distilled some cinnamon bark previously and so hopefully you would have had some higher quality oil to work with and hence get a better yield of benzaldehyde :)
I'll tell you what's amazing and what I use. Dow's High Vacuum Grease. It's silicone grease. It REALLY holds up well under high vacuum because of its low volatility. It keeps its normal viscosity at very low and very high temps -40 C up to over 200 C. It's pretty chemical resistant as well obviously so you don't have to worry about it being attacked or dripping into your flask and messing with a reaction. I can tell you that I never have a problem with losing vacuum even over a course of a very long distillation or reaction. I also use it to seal up my vacuum desiccator and it will hold a vacuum steady for longer than I've ever tested. r.ebay.com/Fr3a0b
Hey, Nile Red, sorry for the unrelated question on the video, but did you remove your mercury fulminate video? P.S.the videos look a lot better in 60 FPS.
I think that the Distinct change in smell from the beginning to the end is (expecting some scientific explanation) Pretty cool. (Oh, ok... Thought he was gonna geek out or something for a little bit :)
A couple of connected suggestions I (and suspect many others) would like to see: _1)_ Nicotine from raw Nicotiana leaves (if possible). _2)_ Nicotine from cured tobacco. Please :-) Preferably methods possible without complex, high end lab equipment.
NaCO3 generates small concentrations of OH. Using something like NaOH would probably drive the reaction to the left. Sorta like allylic bromination. A little bromine leads to radical addition, a lot leads to bromination of the double bond
There probably is an issue about your laptops playback capabilities. All the settings works just fine on my. Be sure to have adobe flash's final version on your pc.
NileRed The problem is that its broken, not that youre, using it. Besides that, fixed it with a blowtorch? What kind of sorcery is that? Did you just smooth the edges with the blowtorch?
Yes, you could do a steam distillation to get the cinnamaldehyde out of the cinnamon, but that takes an awful lot of time and the yield is relatively small. It smells great though.
You have to be a big big manufacturer to be able to extract significant amounts of essential oil. In home lab type of enviroment you probably need 5-10 kg's of bark.
Undead Gaddafi I love how you ended it with the "good smell" comment although you just illustrated how long and cumbersome is the process. you are a cup-half-full type :)
3:04 The arrow in the second part going to the water should be going from the water, as the hydrogen is being taken from the water to change the double bond to a single bond.

When will you be releasing your video on making Benzaldehyde from Bitter almond oil? I would be willing to think that is the easiest method and I just can't wait any longer for the video to be released! :P
So... Would yo have a higher yield of benzaldehyde from the oil of the leaf or bark of cinnamon oil? You kinda confused me at the end there. From what I got from it was that if you used the cinnamon oil from the leaf that has %10 you would get a better yield. Please correct me if I'm wrong.
Most smells are pretty horrid in large quantities; Skatole, for example, smells sweet like flowers until you smell large quantities, then it smells like literal shit.
I just figured out that I have a cinnamaldehyde allergy, and I was wondering - does the cooking of it break it down and make it so different that I wouldn't be allergic? Like... the cinnamaldehyde content in tomatoes. When I eat raw tomatoes, my face flushes burning red. Cooked tomatoes, much less of a reaction. Is this my imagination? Or true?
Why dont you purify cinnamaldehyde too, it's a valuable starting material for various drugs and other chemicals, whereas the major component of the essens oil is cinnamaldehyde, if you want to get benzaldehyde just try to almond oil
The facility were only going to suspend you for shaking it too vigorously??? That's pretty cool of them, really.. I mean, i (briefly) attended, (Odessa Tx.) Permian High School (Friday night lights) gotta say, super snooty teachers; Zero tolerance anything really but ESPECIALLY when it came to shaking it, regardless of vigor used. Expulsion without exception... Ask me how I know. 🤭
Mmmmm...... I would guess that your yield is low. I would think that you're losing product to a competing SN1 reaction where benzaldehyde reacts with any of the other things in the single pot (water and cinnamaldehyde main but nearly everything in that flask can react...). If you increase the temperature above the boiling point of benzaldehyde in the main reaction vessel you could remove it before it had a chance to react with other things. Maybe add a fractional distillation rig to allow the benzaldehyde to "hide" from the other products/reactants. Finally, you should chill your product before trying to separate it. You can actually purify the benzaldehyde out from the cinnamaldehyde and water based solely on their freezing points, but it is slower. Still simply chilling the solution would reduce some other things that were obviously a problem. I think you were getting that cloudy color because your were getting hemiacetal formation.
1) when you make a solution, put the salt in the liquid, not the liquid on the salt: you aren't cooking a pizza. 2) in cinnamon oil there are also cinnamic acid, got by oxidation of cinnamaldehyde, alkilpolyphenols. The pH is alkaline by Na2CO3 so some reactions start expecially when you heat the solution: reaction of Cannizzaro between aldehydes, production of phenols and polyphenols by OH- attack on aromatic ring, genesis of acid and aldehyde by interaction between CO2 (gained by thermal decomposition of Na2CO3) and phenols or polyphenols. 3) if you obtain acetaldehyde, under these conditions goes on aldolic condensation reaction leading to very coniugated systems. 4) phenols are present like phenates and then easily oxidated in alkaline pH; they and coniugated system are yellow as your product.

Benzaldehyde , nitroetane 1F2NP amphetamine
Yo bro I heard you like carbon bonds... So I carboned you're carbon with, you guessed it you have more carbon lol
Are you a Biochem major or a Chem major? Just curious.
Under the last video he commented that he has a biochem degree.
+Anticonny thanks!
Biochem major
I went from the skatole video to this. UA-cam is trying to.....cleanse the palette, I guess. 🤷♀️
Why dont you purify cinnamaldehyde too, it's a valuable starting material for various drugs and other chemicals, whereas the major component of the essens oil is cinnamaldehyde, if you want to get benzaldehyde just try to almond oil
Is the resulting benzaldehyde good grade? How can I make pure food grade benzaldehyde for cooking?
why not using pure cinnamaldehyde u recovered at the end directly with water and sodium carbonate
I'm here waiting for the Nitrous Oxide video.....
wouldnt it be easier to centerfuge it?
wow. seems like a lot of work for such a little return.. no link to chemplayers prep either.
I added the chemplayer prep. Also you are right, a lot of work for very little return
How much did that cinnamon oil cost you?
I got it super cheap. Maybe $15 USD?
So.. we can turn polystyrene to cinnamaldehyde then to benzaldehyde? 😂
Can you make a chemical for me to not feel depressed
Cinnamaldehyde is such a nice chemical :D
The facility were only going to suspend you for shaking it too vigorously???
That's pretty cool of them, really.. I mean, i (briefly) attended, (Odessa Tx.) Permian High School (Friday night lights) gotta say, super snooty teachers; Zero tolerance anything really but ESPECIALLY when it came to shaking it, regardless of vigor used.
Expulsion without exception...
Ask me how I know. 🤭
Hello everybody I would like to know if it is possible to synthesize (Bu4N+•HSO3−) from TBAB.
awsome
Mmmmm......
I would guess that your yield is low. I would think that you're losing product to a competing SN1 reaction where benzaldehyde reacts with any of the other things in the single pot (water and cinnamaldehyde main but nearly everything in that flask can react...).
If you increase the temperature above the boiling point of benzaldehyde in the main reaction vessel you could remove it before it had a chance to react with other things. Maybe add a fractional distillation rig to allow the benzaldehyde to "hide" from the other products/reactants.
Finally, you should chill your product before trying to separate it. You can actually purify the benzaldehyde out from the cinnamaldehyde and water based solely on their freezing points, but it is slower. Still simply chilling the solution would reduce some other things that were obviously a problem. I think you were getting that cloudy color because your were getting hemiacetal formation.
Please revisit this video. ^_^
1) when you make a solution, put the salt in the liquid, not the liquid on the salt: you aren't cooking a pizza.
2) in cinnamon oil there are also cinnamic acid, got by oxidation of cinnamaldehyde, alkilpolyphenols. The pH is alkaline by Na2CO3 so some reactions start expecially when you heat the solution: reaction of Cannizzaro between aldehydes, production of phenols and polyphenols by OH- attack on aromatic ring, genesis of acid and aldehyde by interaction between CO2 (gained by thermal decomposition of Na2CO3) and phenols or polyphenols.
3) if you obtain acetaldehyde, under these conditions goes on aldolic condensation reaction leading to very coniugated systems.
4) phenols are present like phenates and then easily oxidated in alkaline pH; they and coniugated system are yellow as your product.
holy 720p60fps club, batman.
what are stir bars usually made of?
never mind I remembered about Google haha
Usually Steel coated with Teflon.
It looks like chinsee soup flavouring oil :D
Make a chemical rap
