Making an Azodye from Acetone

This one is for all the homechemists out there, finally something u can replicate ;)

Don't conduct any chemical reactions without proper and professional safety analysis and risk management. Measures taken can be invisible, not filmed, not properly visible on camera or misjudged by the viewer due to setup or video construction. Always conduct own appropriate measures regardless of video setup.

Really cool chemistry. Had multiple years of organic chemistry and never heard that you could get a C6 ring from decomposing Acetone

Wow that 100% yield on the last reaction was some next level chemistry

Whenever I have a bad day, I just watch the videos from this channel and drink a shot every time he says "short path vacuum distillation". It always works to lighten the mood

The ending was epic. Some real chemistry YT content there. And this is how you do a 100% yield, folks, take notes.
Thank you once again for your entertaining content and hard work.

Just a friendly advice... Add the stirbar to the flask before placing the flask on top of the magnetic stirrer. The heavier stirbars pose a significant risk of cracking the flask or beaker when being pulled by the sirrer magnet. And in accordance with Murphys law this will happen at step 35 of the 37 step synthesis you have invested your life savings into. Trust me, I speak from experience. 😒

I am an azobenzene scientist, focusing in photoswitchability in condensed state. We think that tight packing due to pi-pi stacking usually inhibits photoswitching. That's why my research is focusing in how to allow this photoswitch in condensed state. Judging from your azo, it seems to be tightly packed. To confirm photoswitching I usually make solution, irradiate, and (1) do TLC (for quick confirmation) or (2) take UV-Vis spectrum (for formal photochromism report)

The separating of the red substance with the sand in tube was epic to see. I was mesmerised by it.

A nice fast trick to crash out amines as an HCl salt: Dissolve the crude mixture in ether. Take a test tube on the side and fill it half and half with concentrated HCl and ether. Then spray the top ether layer through the bottom HCl with a syringe and let it separate. The ether will take up some of the HCl. Then add the top HCl-in-ether layer to the flask with your crude mixture until the amine stops crashing out. Last step is filtration aaaand done! Keep up the awesome work man ! <3

dude this is definitely something to put on a shirt, let me buy it !! ahahah

An alternative to the metal/acid reduction could be thiourea dioxide (TUDO). TUDO is available cheap from indigo dyer suppliers (it's now used instead of sodium dithionite, which cannot be shipped by air anymore) and it's a pretty potent reduction agent providing for a much cleaner reaction than dissolving metal. Procedure usually uses aqueous ethanol as solvent, nitro aromatic and NaOH are first dissolved, followed by TUDO and heating at 70°C for a few hours. The actual reducing agent is formamidinesulfonic acid, formed in situ from TUDO and NaOH.

That was a 50% yield. The second mole of sock was not reacted.

The production value behind your videos keeps getting better every new projects you have worked on!
The dry pan delivery makes it even better.

[djjoeray]

Really enjoyed you having more fun with the commentary on this video - great work on refining the nitration step also!

[petevenuti]

You're like "see it isn't crazy", well, that doesn't matter because it's damned genius, how you continue to come up with stuff that's original, I've never seen in school and could be done at home is absolutely amazing!

3:30 Tar reaction mixture, yellow distillate. Perfect for Tom from Ex&F to see.

[matiastripaldi]

Easily your best video yet. Hope it does well so it encourages you to make more long-form content! :)

[mgritsch]

Omg, I admire your patience with this reaction! Awesome!

[Starwarsfan]

I like these videos! They remind me of old NileRed (not that there’s anything wrong with new NileRed, but it’s nice to see simpler reactions again). I live vicariously through these videos; I was gonna be a chemist, but I ended up going with a different major. I miss doing chemistry, but maybe some day I’ll come back to doing this!

[rob-muntron]

Great video! I have to agree with Thatchemist's advice to dye something after going to all that trouble synthesizing it..
It was a good contrast to see some "novice fabric dye experiment" shenanigans after all the legit informed chemistry :)
I say that with all due respect - how many tie-dying channels are going to synthesize their own dyes? :D
