Today we make methylamine HCl. Very useful in some "fun" syntheses but used in many applications overall. Enjoy!

    Seeing the garage doors in the glassware really brings it all together.
  • @That_Chemist
    that 'distillation' is one of the undergrad moments of all time
  • @MikeyMobes
    27% yield is good without a proper schlenk line setup. In the world of inorganic synthesis thats a solid yield. All that smoke and fog is your hygroscopic reagents reacting with water lowering your yield. Nice work!

    Psychedelics are just an exceptional mental health breakthrough. It's quite fascinating how effective they are against depression and anxiety. Saved my life.

    Excellent video! Now all I'm left to wonder is how the hell you got Brilliant to sponsor a List 1 precursor synth, lol. Great content, keep it up man!

    this reminds me of taking chem in school. at the end of the year i realized my chem professor had taught the entire class about making meth. every unit focused around one of the steps of production for meth, but was focused on teaching the chemistry. he never acknowledged it and just laughed when i asked him about it later

    Instead of using a funnel in the HCl try using a small glass tube. Bubbles would be smaller and provide more surface area for the gas to react.

    The main reason these street drugs kill people purely has to do with them being illegal (as most deaths are caused by unknown purities and unknown other chemicals added to the drugs, as well as violence surrounding the illegal sales). The deaths involved almost never have to do with the pure form of the chemical itself, but a deranged, toxin filled shitty street version of the chemical. If these drugs were legal, and regulated, people would know the doses they were consuming, know the drugs were pure, and there would be far less violence associated with illegal sales and use. (Also less wasted on EMTs, less wasted on cops, less wasted on holding people in prisons for possession, all of this could go into free drug rehab centers instead) Decriminalization isn't enough, as it only solves half the issue, considering that people will always use drugs, they really need to be fully legalized and regulated. (Like cannabis, tobacco and alcohol) People don't truly care about deaths, harms and costs to taxpayers though, because if they did, it would be legal already, what people truly care about is the puritanical punishment of those they subjectively deem to be morally inept.
  • Just came across your channel while looking for an extraction tec for something totally different. And this is the best kind of chemistry videos on YouTube man keep her up 🤘 got a lifetime subscription here today.

    when smelling something you should wave the smell over to you, that way if it knocks you out you don't fall on the lab gear. also you lower the amount that gets to you so the cancer probability is less. it was good that you did not hold the bottle.

    I used to work at chemical plant as an apprentice and I've never been more fascinated in my entire life! I was lucky to work up from a cleaner in just about 7 months, I'm not an idiot and I was obviously interested so they gave me a chance. I was lucky to work in a plant that was a "problem solver" so we there were only a few products that we did over repeatedly, one was refining oil for a Chinese company that was an anti-knocking compound. It was £1000/Ltr so we had to be careful. I didn't do any additions/reactions at that point, just dis/charging filters and drying in all sorts of impellor dryers and a kind of spin dryer. I loved it but my back gave out so had to quit. I really miss it, and could've punched myself for not doing better at school.

    Very well put together very enjoyable to watch thank you
  • @s0kulite
    Excellent production, Bravo Vince!

    SWIM says that the best way to get a good absorption with the "distillation" here is to use an aquarium bubbler stone, one of the big long ones, at the bottom of a jar mostly full of glass marbles or those weird ornamental glass pebbles they sell at craft stores. That breaks everything up into super small bubbles, generates plenty of turbulence, and slows the bubbles down enough to SIGNIFICANTLY increase yield. When SWIM was concentrating ammonia for making touch powder, that worked really well.

    My dog, Jessie, woke up and walked over to me at the beginning of your video. She hasn't done that since I was watching the Bald Science Man show. 😂
  • The easiest reaction is with formaldehyde combined with ammonium chloride and reflux it for a while. Make sure the ammonium chloride is in 2x molar excess and you will get nearly pure methylamine as your product with some ammonium chloride that will crystalize out of the concentrated methylamine. If you want dimethylamine instead simply use a 2:1 molar ratio of formaldehyde to ammonium chloride.
