    Hobby chemistry in a nutshell:
    "This synthesis uses A, B, C, D and E. The first four can be easily bought, but E needs to be distilled from F and G. F can be bought but G can be made by reacting H with..."

      @@kadergumus2598 Now you need a different A, B, and C. A and B are about 50 cigarettes each, but C can only be purchased with stamps, so you need to synthesize D to sell for stamps. To get D, you can either have a guard smuggle it in, synthesize it with B, E, and F, or recruit some fellow inmates to acquire it from some other inmates. YMMV though; my yields have not been great.

      If you consider the 85% expected yield, times two recrystallizations…
      100x.85=.85 first pass
      .85x.85=.72 second pass
      So a theoretical 72% compared to the 70% actual is negligible.

    I did this reaction in my organic chemistry lab class, and I used almost the same method you used in this video, although with some small variations.
    Our benzaldehyde and ethanol was analytical grade, and we purified our acetone (technical grade) through distillation (to remove water contamination and other impurities). That could explain why you had that initial cloudiness in benzaldehyde, probably your benzaldehyde was not so pure. To recrystallize the product we used the first method you used, hot ethanol (in the right amount to dissolve all the product), then we added room temperature water (while ethanol was still hot) until complete cloudiness occurred and then we cooled down the solution in an ice bath.
    Eventually we vacuum filtered the precipitate and dried it in the oven. My yield was 78,2% of raw product, 73,9% of target molecule (we analyzed it through GC-MS and UV-VIS). Not the best but I'm still and undergraduate so totally fine for me.
    My guess is, as you already aknowledged in the video, that you used too much ethanol and much of the product was still in the liquid phase, though your yield was not bad at all.

    When I did the synthesis, it actually went nearly like the clock reaction you mentioned. I dont know why does it happen, but it is pretty cool. I add the acetone and then stirr, and suddenly a ton of stuff falls out of solution after like 60 seconds and the content goes from light yellow to brown-orange and looses transparecy.

    • @sleepychemist2701
      @sleepychemist2701 7 ปีที่แล้ว +11

      The bittering additives are usually in the ppm range. The rest of the 5% is generally water generated from the distillation process (ethanol forms an azeotrope with water at 95%). So, the 5% really isn't a huge concern. I'm sure if, after recrystallisation, the product was put on a high-vacuum line at RT for 24 h and a proton NMR taken the only residual protons that would be seen are from the ethanol and from water. The additives won't even be detectable.

    I would love to ask something... I went through few laboratories at our university and we never put the watchglass on a beaker during recrystallization... The true is, that it was almost forbidden to use beakers for reactions, heating and so on... We could use it just for our solutions of acids, bases and salts. We were using just flasks for almost everything. I just want to ask, why there should be watchglass during recrystallization... Thank you for answer :)

    E.g. change their colour, or get hard, or becoming more conductive/resistive to electricity, or more/less soluble in water or some other solvent?

  • @karpatikende2258
    @karpatikende2258 5 ปีที่แล้ว

    In my opinion the crystalization did not work because at the vacuum filtration point you did not wash the product with ethanol-ecatic acid mixture and you got an oily mixture at the crystalization point. I am a student and in our lab it is a typical problem when somebody skips the ethanol-ecatic acid washing step.

    You should do a video on the easiest way to get very pure NH4ClO4. Amateur rocketry guys often don't have the chem knowledge to make it, so we use oxidizers that you can buy in OTC products like KNO3. I would appreciate any videos on propellant useful compounds too, things like Li, Na, and K nitrates and perchlorates :)
