Dude you have such an amazing amateur lab!! Seeing that same mat i now use, and the clean looking hood on that nice bench with the tank safely chained up... thats exactly what i was aiming for over the next year. And oh my god, that retro looking cooling recirculator pump is something ive dreamed of for years but ultimately realized I'll have to learn how to build one from the old AC i saved. Im just scared to
Thanks! This one is just from youtube music, I went through a few genres/moods and saved the ones I liked. Agreed though it takes forever. I just looped one song for this whole video but it's mostly quiet enough to be unnoticeable 😅
The "delta H" instead of a "delta T" at 5:52 hurts my eyes But the rest of the video was pretty good, I'm curious to see how you reduce the aniline to good ol benzene
Still an advocate of the sodium benzoate decarb route. It is straightforward, reagents are super cheap, and I was able to get it to work with a 380C heating mantle using 1L paint cans as the vessels. From 300g of benzoate and 180g of NaOH, separated into 3 batches, was obtained ~120ml of clear pure benzene (had to redistill twice)
What do you think about heating the flask with PABA with a burner? As far as I can see, it can lead to a somewhat higher yield of aniline without tormenting the hotplate and/or the flask itself
@@nomcopterlabs I used glass at temperatures as high as 340 C. Glass can resist high temperatures, but it doesn't enjoy sharp temperature difference. You can try using a gas burner if you've never done it before, it's an amazing tool!
The trimerisation of acetylene (ethyne), by leading it through a red hot iron pipe, is the Reppe synthesis of benzene. I wonder why nobody have done it on TH-cam? I have only tried the decarboxylation of benzoate-Na, by dry-distilling with lime. I'd buy it pure, if I can't use toluene, xylene or ethylbenzene.
Probably because that sounds horrendously dangerous lol. Acetylene and oxygen mixtures are notoriously explosive, so I don’t think it would be very forgiving of mistakes.
@@FullModernAlchemist As a kid I did a lot of experiments with acetylene from Ca-carbide. I never had any problems with my home lab acetylene burners.. I never mixed it with pure oxygen, however, so I always got a lot of soot. As far as air is containing oxygen, it's just not a problem.
Forgive my ignorance, but the video title gives the impression that your turning the Vitamin supplement into Benzene not Anilene. What did I miss here?
It might be easily replaceable, but in some cases it can't be and Benzene is absolutely required in many reactions that use it as a reactant. Yeah, in a lot of cases Toluene can be used, but not in all of them and Toluene is banned in a lot of places. Like in Kentucky, the sale of Toluene is prohibited due to its use in illicit drug manufacturing.
Benzine isn’t as scary as people say it is. Yea it’s toxic…. Nowhere near so as mercury salts or sodium Cyanide. It’s probably not as cancer inducing as a lot of other things, at least in the quantities and scales used in the home/amateur laboratory and even the research lab.
Yeah that's why I'm not too spooked to make it. And gasoline has ~1% benzene - it's where a lot of its smell comes from. So we all get incidentally exposed at the pump.
The structure formula is wrong. What you have drawn is cyclohexatrien. Benzene has a delocated pi-electron system instead of three located double bonds.
chemical formulae must serve chemists, not vice versa. nut-like benzene would be appropriate if you're trying to stress the difference between non-existing cyclohexatriene and benzene, but in any other case it's just ugly and inconvenient for almost anyone
@@dimaminiailo3723 Your profile shows me it's an important topic for you. I know professors who explicitly say to draw distinct double bonds. In some cases drawing aromatics with a circle can be seen as false. You can't draw molecules exactly as they are anyways. If the ring is supposed to show that every bond is equal it wouldn't make sense to use it for other aromatics (besides a few) because every substituent causes a change in the pi-system.
And here I was making aniline from my valuable benzene/nitrobenzene. This is clearly a FAR superior route in every way, thanks for sharing!
Yeah so much easier!
Liking the longer videos brother!

Liked the clip. Aniline is useful to make dyes and antibacterial sulfas.
Pocket reduction method also works 🗿
Nice video you made anyways. How do you select music? It´s something i struggle with a lot lol

Great video! Glad to see you posting again as well! Keep up the great work!!! 😃💯
I've heard of this synth but haven't tried it yet, great video!
Very good! Please make benzene from acetylene gas

It would work but would definitely put more stress on the glass and it doesn't need to get that hot - it was reacting fine at ~220C

да ты волшебник! 🤗
Good job i whant part 2 🎉🎉❤
Dope!
No copper catalyst? Like copper chromate or anything...
Yeah amazingly none needed!

Astral Chemistry made a video about it

Fun chemistry exercise, but realistically there's barely any use for benzene that can't be fulfilled better by Toluene.
It can be useful feedstock for a few reactions - but one of the main ones is aniline which is this first step anyways 😅

@@BackYardScience2000 Unless you're making a metallocene of benzene, I can't see any situation where Toluene doesn't work.
