      Liquid gas column extraction of organic compounds? I’m told that’s something you should definitely do outside!

          Alcohol isn’t that great as an organic solvent. Are you using the air fryer to evaporate? That must be a fair fire risk!

          Butane on the other hand is a good organic solvent and will evaporate at room temperature (just don’t evaporate it in a room or near any heat source).

            I’m happy with it - i feel like the extraction i get is pretty good for the ease and safety of my little setup. I’m not trying to make enough to sell, just mostly making cheezits and candies for friends. When i do have a lot to process i usually do a dry ice shake.

    For me it has been etching circuit boards and specifically making my own liquid tinning solution at one point. I mostly do hydrochloric acid/hydrogen peroxide on larger stuff and ferric chloride on smaller prototypes.

    Steel etching with Winsteard’s reagent. It is a bit dangerous because if done wrong it forms explosive dust. It was also long and tedious because the liquid must be near boiling and stirring so it evaporated quickly and has to be topped off and brought back to temperature often. The etch itself requires a long temper of a quenched sample and has an iterative process of etching and back-polishing to gradually remove surface roughness but leave the slightly deeper grain boundaries.

    It took several hours of preparation and several hours of active work per sample and even then had a 50/50 success rate. I was professionally trained by a third party who learned this process from the person who perfected it, George Vander Voort.

    I’m surprised that nobody has done an extraction of organic/aromatic content in an oil/fat ? Have you never backed some “space cakes” ? I haven’t but I’ve seen people doing it, and it’s pretty advanced chemistry when you think well

        Bottles of carbonated beverages can handle up to 150 psi. Semi truck tires are pressurized to 110 psi. Freezing water in a pop bottle can cause it to explode, think about that!

    Extraction and purification of surface residue for triple quadrupole analysis looking for pesticides, or inductively coupled plasma optical emission spectrometry looking for arsenic, but that’s practically physics by that level.

      I don’t do that much of that but I hear my guts can do some amazing chemistry on the food all on their own, not to mention the cells themselves.
