Great video. Here's a couple of points that could be useful for improving the method: (1) I've seen some sources suggest that deprotonation of salicylic acid aids decarboxylation due to the competition for the proton. This should also stop the esterification as the carboxylate is not electrophilic. (2) Before nitration, protect the phenol with either acetic anhydride or (acetic acid + HCl + boil). Do the nitration using c. sulfuric acid as the solvent, and 1.1 equivalents of NaNO3, at -5 degrees Celsius (ice/brine bath), then hydrolyse. It adds two steps; however, this will lead to a selective mononitration to p-nitrophenyl acetate. Also means you avoid forming nasty di(-) and trinitrated products, which will be explosive. Work it up by pouring it onto ice and water and filter in vacuo. The crystals you get out will be almost exclusively p-nitrophenyl acetate. (3) The decomposition of p-aminophenol is due to oxidation/polymerisation in light, but it actually amounts to very little (if you check by NMR etc), so long as you keep it out of solvent. Recryst. from water is the usual way of purification, but I found that toluene works well too (if you can get your hands on it). (4) Recryst for p-aminophenol should be easier than for paracetamol.

3:48 you should be aware that this is a yield of 94g of a mixture of ASA and salicylic acid. The recrystallization step almost certainly hydrolyzed a substantial amount of your product, not just a few percent. You can confirm this by using the iron (iii) chloride test for phenols. You will obtain a colored adduct with your recrystallized product, confirming the presence of a phenolic hydroxyl group. I know this because I synthesized ASA from salicylic acid and acetic anhydride, and after quenching the reaction mixture and decanting the precipitate, the crude product was recrystallized from boiling water. The melting point was extremely broad, strongly depressed, and was dependent upon the rate of heating. The NMR spectrum was a mess but did demonstrate the aromatic protons around 7.2-7.24ppm, and FTIR showed a broad and intense absorption around 3300/cm, and a sharp, very intense peak around 1710/cm. This is all immaterial, however, since your next step is to hydrolyze any remaining ASA.

Do be careful with the phenol. It's quite hazardous: Around a tablespoon on the skin can be fatal, and the burns it causes are painless so you may not notice that you spilled it on yourself until it's too late. Another concern is that trying to wash it from your skin with water tends to just spread it and increase the area of skin that is damaged- you must instead wash it off with glycerol or a solution of polyethylene glycol. I certainly wouldn't handle that stuff without a lab coat on!

So there's a kind of coffee maker that used to be used a lot more, called a vacuum pot, which is essentially a self-contained vacuum filtering setup for extracting coffee. It's crazy to me how much a vacuum filtering device like the one used here looks like it when the flask is attached. Basically it consists of a flask-like carafe and a filtering bowl that has a long glass tube that goes down into the flask, with a rubber gasket between the two and one of various kinds of filters in the bottom of the bowl. Water bubbles up into the top where it is mixed with coffee, and eventually air bubbles out through the tube too and is not replaced. With the proper timing, you can develop a really good low pressure environment inside the carafe that sucks the water right out of the coffee grounds as the carafe cools. It's especially cool watching water boil below 100 c in the carafe, if you get the pressure low enough.

[@kayjay7585]

I'm totally intrigued and I googled "coffee vacuum pot" and got: "The vacuum pot, also called the syphon, is a beautiful and flashy way to make great coffee. Invented in Germany in the early 19th century, it's a full immersion brewer that also employs a metal or cloth filter, so you end up with a full-bodied and clean cup. " is that the device? There are some new models for purchase for under 100 bucks!

[@georgeparkins777]

@@kayjay7585 Yes. But I use the kind with a glass filter rod. It's hard to explain what that is but essentially it's a glass rod with a bulge in the middle, and that bulge is covered with bumps or burrs. The rod is held down by suction and the bumps make contact with the bottom of the filtering chamber, forming a coarse filter that allows quite a lot of liquid to flow past it but not medium-grind coffee. The cheap models have a reputation for being fragile. Mine are both 1950's and more resilient. I plan to give them to my children if I ever have any.

He then lets us write a test, and that's the content of his lessons. He also likes to shout so loud that you can hear it rooms across and he likes to smash objects against furniture (or furniture against furniture) to release anger. I'm glad we never have access to chemicals right now. I wouldn't want to be in a room with him handling corrosive or toxic substances, he'd probably throw it across the room.

your videos are really calming for me somehow. And i learn a bunch about my favorite kind of science along the wayy so perfect combination. Thank you for doing these videos! :) they help a lt especially now

Interesting synthesis. It's the most precious Tylenol you'll ever have! This video is a great mix of innovative low tech solutions and good lab skills. Unfortunately your yield really supports the saying "a day in the library saves you a week at the bench." You made a bunch of rookie mistakes choosing when and how to execute your steps. Thats why you got the low yield. One thing I found particularly strange was your choice of reduction conditions. You are kind of halfway between two different types of reductions using research lab type reagents, whereas you could have done a dissolving metal reduction easily with household stuff. Be really careful with your Palladium on carbon waste! Once its dry, or combined with just a bit of paper or organic solvent you can have a fire.

[@KnakuanaRka]

Myron Wilde Could you be a bit more specific about what was wrong and what he could have done better?

[@RobsMiscellania]

@@KnakuanaRka I'm trying to remember what he did without watching the video again - if I remember right, he used sodium borohydride in a basic solution with palladium on carbon. Interesting choice. Looked like the reduction went okay enough, but Myron is right, the number of steps, such as where he filtered it and the color changed during, so he refiltered it and it changed again - product was being destroyed every moment there. Other things, mechanical losses, solvent losses, and so on, could contribute to low yield. Although I'd have been happy to get two or three grams out of the initial investment of 100g of precursor. It is several synthetic steps, after all.

[@mealex303]

Didn't look edible? Is there a way of finding out its strength ?

[@orellaminx3530]

Watching a video like this makes me want one long ass video of you just cleaning all your glass after a project.

[@wheremakeysat]

This takes me back to organic chem lab. Love your content, keep it up!

[@danielwalker26]

Would love to see you explain how a flame less ration heater, like from an MRE, works then make one of your own.

[@lekoman]

That's a super simple reaction. It's just oxidizing a ton of really fine iron shavings with water. Basically, the fineness of the iron shavings means tons of surface area, so the reaction can happen really quickly. You're making a bunch of rust happen really fast, and rusting is exothermic so it gets hot. Bingo-bango, you've got hot food.

[@StuffBudDuz]

Turns out creating Tylenol is quite a headache.

[@1stPCFerret]

Fascinating! Although, if I get a headache, I'll just take the Aspirin. 😁

[@sleepful1917]

i love that purple color at 19:05 - unintended consequence no less

[@sombrashibe]

As someone who takes migraines medications that has APAP in them, this was a fascinating watch! Thank you 💖

[@devinsn2]

I know that what youve done here, I can't do and it's amazing. That being said, I can't help but think of " this coke tastes like pepsi"

[@Gorboror]

24:41 Why I watch your videos, even though, a lot of the times, I don't understand it.

[@xXTehnXX]

could you have kept it as an ester instead of a phenol when you added the no2 group so the ortho position would be sterically hindered so the reaction further favored no2 addition at the para end?

[@TheAlmostKingOfPotatoes]

I don't know anything about chemistry. But what I've learnt from watching you is re-crystalization always messes up the yeild. And that you always do it.

[@jaratt85]

If you are like me and wonder what -nitrophenol can be used for.. It's mostly used as a dye or for curing leather.

I've been slowly binging your transformations playlist, and just before starting this video, i sprained my ankle. So I could really use some of that stuff right about now

[@picodellamirandol4418]

Nile, I'm a big fan of you but I'm very annoyed by the "it's just a bunch of filler junk" thing about the excipients you said at 1:30. It's not just a bunch of filler junk, it's work, it's research that in some cases can permit the explanation of the therapeutic potential of the active molecule. I respect you for your work as a chemist, pay respect for the technologists.

[@elisabettabianchini290]

Clap clap

[@Owen_loves_Butters]

The filler may be necessary, but it's still basically junk for what he's doing.

[@Chrissy4605]

Wow, I hope you didn't get a headache from this project!!! I love listening to your voice!!! Purple Chrissy

[@dexter2392]

Really cool. A video of full chemical synthesis will all the steps and difficulties described. Thank you, as a person who's very interested in that.

Sometimes I wander how fast I would die from drinking some of the things you show in your videos

But some of the things look so appealing haha

22:55 "I probably lost most of my product doing the multiple recrystallizations." *Proceeds to show mathematical proof that he lost most of the product in step 4.

[@GodlikeIridium]

Yeah... The decarboxylation and the nitration are both very inefficient. But the yield of the acetylation in the end really surprised me. But is probably caused by the small scale and the 3 recristallisations. Really nice video. A similiar video making caffeine would be nice.

[@bellabear653]

Kids today are so lucky to have your videos and teachers especially in high school should take advantage of this to inspire young minds.

[@SianaGearz]

Edible Chem session on that Paracetamol?

[@TrabberShir]

In a process like this, making things with food (or pharmaceutical) grade purity is a really expensive and time consuming proposition.

[@SianaGearz]

Ooooh right. But i just love it when NileRed swallows his own chem!

[@TheLinkoln18]

But neither Aspirin or paracetamol are edible, granted not harmful in low quantity, but they are both very toxic.

[@thewolfin]

The initial reagent might be edible, but all the other reagents (such as hardware store hydrofluoric acid) probably aren't.
