    I don’t have the materials to do your experiments but I love how you put real research into them and keep the video organized and informative yet concise. Thank you for the videos!

      Thanks so much! It took a lot of research to finalize the experiment. More than most of my experiments.

    Always enjoy your content. How many units of water should have been coming over per unit of formaldehyde? Looking back on how it went, do you feel it would it have been better to bubble the condenser output through a little water?

      The amount of water is hard to measure. If more water came through we would end up with a 37% solution, but less came through so evaporation was a problem. I don't think I would change anything as I was trying to get as pure of formaldehyde as I could. Even with the losses it was educational.

      Agreed it is very informative, people see the intricacies of the chemicals behaviour and the highs and lows of the whole approach - valuable.

    Do you write and draw all the info on the boards? If so, you have excellent handwriting for such a smarty pants!
    God bless and thank you for making these videos. I still get excited to see a new one!

    Unless enough water was coming over with the formaldehyde, its VERY likely that it was staying a gas, and venting out of the distillation apparatus

      @cranialconstruction2218  2 หลายเดือนก่อน +1

      Yes, I agree. I was discussing that during the video. However, plugging the vent hole made a dramatic difference thankfully. I was surprised at the purity of the formaldehyde and didn't expect it to evaporate like it did. I've never had that happen before.

      @@cranialconstruction2218 oh, interesting. would adding water to the distillation flask before distillation be an issue? if so then i imagine bubbling the formaldehyde into a collection flask filled with water would improve yield.

      You can just buy formaldehyde. No need to buy it. For other oxidations you can just use chromium trioxide and 37% H2SO4 which can be easily made from 15% H2SO4 which is not regulated

    The early lab methode was first synthesis of methylal C3H8O2 Methylendimethylether. bp 42C from Methylalcohol and MnO2, H2SO4. The methylal was mixed in great excess of H2so4 and destilled again for formaldehyde. somehow directly doesnt work or doesnt work so good. may be an try worth.
