8 years ago: remember, this was made in a lab, so you should not eat it, or even try it. Couple years ago: I'm making grape flavor from vinyl gloves. It tastes ok, but if I have enough, it will keep all birds away and possiblykill them. Next week I'm going to make water out of diamonds and drink the most expensive water ever Today: I am renting an island to make the smelliest chemical known, notorious for making an entire town vomit and getting even more noxious as the chemical is diluted and dispersed. Good thing the nearest houses are 200 yards away, down wind. Tune In next week when I drink paint thinner I have converted into cherry soda

Mushroom flavored candy

Something about watching these reactions is very relaxing.

When you said you would keep it basic, you lied its acidic.

I remember doing this in chemistry, thank you so much for your video man! All it really did demonstrate to me though, is how much I've seem to have forgotten of my chemistry knowlege...

Congrats Nigel, this video is being used by my Ochem 3 professor as a demo video!

what a lad, keeping it simple and explaining the chemistry behind it mah boi

Love your content! Finally taking organic chemistry and we're using this for a lab!

I performed this exact experiment in my lab. When adding water to the solution to neutralize acetic anhydride, the solution in my round bottom flask boiled out (pretty much exploded out). I was able to save some of it to get the final product. Furthermore, maybe warn the students to use a dropwise neutralization of the acetic anhydride. Really pungent banana though! That was fun.

my name is ester

Thank you sir. This was very helpful! From a chemistry teacher in training

Nice! Just what I needed for my 3,6-dibenzoylmorphine reaction...

I tried my hand at home distilling ages ago; often there would be a strong banana smell to the distillate, but only a few milliliters came over before it cleared up. All manner of stuff before and after the ethanol and even some furans for afters. Mmmm, wet cardboard smell! Keep yer cuts clean, boys!

I liked the colors, helped me understand what is going on

It do really reminds me of my time in the Lab.

Nononanol -- doo dooooo dadoodoo

Did this for octyl acetate. Doing this with longer alcohols will mean you will lose less of your product in the washing steps but will require a higher temperature to distill at the end. For my reaction, I used 30mL of 1-octanol. After the reaction and washing steps, I dried the crude organic layer over MgSO4 for 15 minutes and filtered, then used an impromptu short path air condenser (made using the 75 degree and 105 degree joints with a short glass tube connecting them), then distilled the mixture under vacuum to yield 25.18g of crystal clear octyl acetate, 77.0% yield.

You made me crave flavored mentos... So you made mentos. :)

I don't need any more banana flavoring. Trust me.

I want some question in the video if use 2-penthanol is banana flavor, benzyl alcohol is peach flavor and etc. But in the video, using 1-penthanol then final product is banana flavor. Can I use either 2-penthanol or 1-penthanol for make banana flavor?

Cool

I did a similar, much simpler experiment today in class. I added the Sodium Carbonate to my mixture too early! Literally, all the liquid just spilled out of the test tube :( Lol

Yeah, let me just go grab the acetic anhydride that I got from the walmart.

I made isoamyl acetate today, smells like candy banana :)

Great vid! Is there an easy way of getting some of the alcohols?

Nice

Benzyl acetate is a major component of jasmine. Some say it has a floral odour.

i did this at school but with ethanol and butanoic acid to make pineapple

@nilered Hi Nile, your videos really revigorished my passion for chemistry, after forgetting about it years ago. I'd like to know, where did you buy the heating mantle used in the video at 6:00 ? I'd greatly appreciate~ Thanks Sofiane

Maybe a Fischer reaction between BnOH & GAA could suffice? I made EtOAc once.

Is there a specific name for the thermometer adapter your using? I have been trying to find it forever, hate those cheap screw on ones.

Would glacial acetic acid work instead of acetic anhydride here? The anhydride should be made in situ no? Or another mechanism should intervene but in the same way as ethyl acetate can be made from ethanol, glacial acetic and H2SO4. Just my guess.

TL:DR video shown makes the scent of apples, not bananas. Neither 1 or 2 pentanol would yield the isoamyl acetate for bananas. Probably been covered but I can't see any mention of it in any of the recent comments so here it is. What is made here is known as amyl acetate which has a scent of more like apples. In order to make the true scent of bananas what you need is isoamyl acetate made from isoamyl alcohol which is a completely different substance. Then I have no clue as to where he got the 2-pentanol from because that would make sec-amyl acetate which I couldn't find any literature on its odor but that could be an interesting experiment. Though from what I can tell the other alcohol to acetate scents are accurate.

The carbonyl gets the H+ from h2so4 then the -OH from the pentanol attacks the -OH cation formed to stabilize it, and so o n..

@NileRed "Certain species of honeybee release a pheromone, isoamyl acetate, when the ovipositor is pulled from the abdomen after stinging a victim. This pheromone attracts other bees to the victim and thus incites multiple stings." Would you be willing to test the effectiveness of laboratory-created isoamyl acetate and whether or not it agitates bees in some way? I am wondering if a time I got randomly stung by bees had to do with banana flavored candy that contained isoamyl acetate falsely triggering this sting response.

We just made banana oil in organic chem lab in uni...

So... How do you go about making this edible?

I'm re watching this video and I was thinking won't there be water in the end because the acetic acid can make more ester with the alcohol

could you make a video of dioctyl maleate synthesis

do any changing the brach of the pentanol in this reaction replayme brother

Thank you for the video. I have no experience in Chemistry but i'm interested to make flavor for beverages. Is this process same goes as to make them? And also, is there a book which you can recommend me on how to make flavor to use for food and beverages?

You should consider redoing this video, but with all the listed precursors. :3

Just mix ethanoic acid with ethanol in the presence of conc. Surfuric acid and you have your ester

I was thinking he made a mushroom lol

Where do you get all these chemicals? Acedic anhydride is hard to get cause it's used to make heroin from morphine.

any idea what the fake rootbeer compound in 'rootbeer barrel' type candies might be?

could you use methanol for this reaction or larger alcohols or mabe even phenol? i am just wondering.

I recently acquired some n-hexanol, and I must say that in very small concentrations it has a very "mushroom-ish" smell to my nose (not in a good way).

Hello¡ amazing video. I am required to do a scientific report on this video and required some additional information to completed. Is there a way one can contact the video creator?

Why did you list 2-pentanol as giving a banana smelling product in the table at 1:00 but said you were using 1-pentanol? Was that a typo? Or was there a specific reason you went with 1-pentanol instead of 2-pentanol?

Can ANY smell/taste be replicated artificially through the science of chemistry??

Can you do all these esterifications with glacial acetic acid and the alcohol, and then just distill off the ester?

So then, how do they make it if not in the lab?

Why use H2SO4 as the catalyst? Why not Carbonic Acid? or any other acidic catalyst? I'm an IB student and was thinking of comparing the % yeild, the rate of reaction or any other quantitative independent variable based on different catalysts for my HL Chemisty IA. Esterification reactions just happen to be one of the coolest potential reactions for me to compare with a catalyst.

I know as benzyl acetate smells jasmine

Edible chem? Or smellable chem?

cant i use acetic acid insted of acetic anidryde?

what is a good source of benzyl alcohol? i really would like to know.

please consider doing an experiment synthesizing methyl salycilate from pepto bismol with minimum waste.

Will it work with dil. H2SO4 as well?

ah sure, let me just FUCKING BOOT UP MY TRUSTY NMR MACHINE THAT I HAVE LYING AROUND AT HOME

Use a NMR for that compound is really excessive and expensive. An IR for functional group is more than enough

How do you make acetic anhydride from glacial acetic acid? Can you just dehydrate it with sulfuric acid?

"You should not eat it" bro what happened.

Can you use glacial acetic acid instead of acetic anhydride.

Gotta activate the electrophile in that mechanism discussion, brah

you shake a separatory funnel like my grandma

i wan to make butanone form n-butanal can you tell me how to do it?

If you used acetic acid instead of acetic anhydride, wouldn't you create the pentyl acetate and water instead of acetic acid?

Are you making mezcal?

Are parts of that video sped up or is the experimenter just manic? ;-)

What smells does it give if you use ethanol or methanol ?

Or better known as ethanoate esters.

Juicy Fruit gum?

Syrian rue extract crystal how to make recipe video?

Everything would be fine, but acetic acid anhydride is a substance that is almost impossible to find. Such reactions should be preceded by a video about how to find or make acetic acid anhydride.

wait did you use 1-pentanol or 2-pentanol because it says 2-pentanolt 0:48

Why not just make it from salicylic acid? It's much eaiser and there's a salicylate ester for every scent or flavor. Natural scents and flavors are litterally due to salicylates present in fruits and herbs.

Can I use separatory funnel instead of dropping funnel?

are all artificial flavourings as safe as natural flavourings for human consumption?

can u made it risinine from castor beans?

for the distillation at 6:00 you're using a special teflon Quickfit for the thermometer, can you tell me where i can buy it?

What would isopropanol, methanol and ethanol create?

Why not just take acetic acid and alcohol?

Mushrooms smell?

Why isn’t this in edible chem?

"this was made in a lab so you definitely shouldn't try it"...... I mean..... I bet it's safe.

Reading a RedBull can got me here.

WHY didn`t you just use glacial acetic acid instead of that precious acetic anhydride ?

It sounds like fun at first but you can open up all the windows in your house and that shit will linger for days

Is it actually with those flavours, or is it only with those aromas, and it actually tastes horrible?

Can i use this for vaping?

Mushroom smell?

I think you used the outdated naming system

I'm assuming these are not food safe, either.

Acetic acid sounds like acidic acid.

One can work at a school lab, or one can live in Canada...

What’s the point of making it if you can’t even try it :(

Shaken not stirred

I’ve done worse (thousands of times worse) than eating the stuff made in the lab.
