- /u/socat2me 3rd August, 2022 - 13:00 Ahhh I gotcha ok. I've written a lot of elaborate guides for this kind of stuff in the past but really it doesn't need to be so crazy. Here's a post that I made about acetone washing for ketamine: /post/e29f98463ec01c17e698 You can use the exact same procedure. When you're using large amounts you are going to want to use a pipette to draw off the liquid layer. You can buy glass serological pipettes and hand pumps on amazon for fairly cheap. I always recommend the ones with the colored handles. The red one is 25 mL which is generally going to be too much, either the blue or green (2mL and 10mL if I recall) ones are going to give you more control to keep you from drawing up product on accident. I recommend you get either ACS grade acetone from online or specifically klean-strip brand acetone, which can be found in the pain section of walmart or other hardware stores. If you live in an area where you can't get this brand, make sure you check the MSDS first for whatever product you're buying to make sure there are no additives listed. Because the MSDS isn't always 100% reliable you also want to do a test of the solvent by evaporating a little bit on a surface that you'd be able to see any residue on, like a glass tray. It should evaporate clean leaving nothing behind. It's much easier than dealing with filtration. If I can avoid it I never do buchner filtration for home chemistry. Sometimes I'll do the reverse though. Throw in a cotton ball and draw up all the liquid through that.

- /u/socat2me 2nd August, 2022 - 23:06 Honestly my advice would be to not bother with it for 2g man. Recrystallization to get the kind of crystals you are probably looking for is a real bitch and the process inherently loses some of the product to the mother liquor so you won't get 2g of crystals even if you actually pull it off. The only reason to do this would be if there's some impurity you really need to remove. If you want to try cleaning it up you could acetone wash it. In my experience that removes the brown residuals from the safrole compounds. Most of the brown sand-looking MDMA I've seen was still high quality btw. If you bought it locally then I can't say, but if it came from a market then it's probably high purity. Some of the best stuff I've ever had was in a fine powder like that, it wasn't crystallized.

- /u/socat2me 19th October, 2022 - 00:44 Not quite what I was doing, I spent years working in an organic research lab during my time at university. Xylene and MEK suck, hence why I said absolute worst case scenario. If we're talking ideal solvents though, naphtha is certainly not a solvent you'll find being used in a laboratory setting, it's just readily available and an easy choice for home chemistry. Although I'm not really sure what you're referring to in regards to CaOH? Not that a strong base is really required for this reaction but It's quite strong. The water solubility is low but the strength of a base is inversely proportionate to the strength of--and directly proportionate to the stability of, the conjugate acid. In this case a calcium ion, hence strong base. The poor yields that people get are probably due to the poor water solubility, so the ionization isn't great and thus neither is the reaction rate. As I mentioned though, I was able to get essentially quantitative yields by increasing the temperature. See van't hoff or arrhenius equations for explanation of the temperature dependence on reaction rate. Really you can substitute all kinds of stuff because of how simple the reaction is. It's just an acid/base reaction on an alkaloid with an easy extraction workup. No need to think too hard about it, as long as you don't do something crazy yields should be close to quantitative for any of these reactions.

- /u/socat2me 16th October, 2022 - 10:38 Nah you're good to use it the production process is pretty straightforward with that stuff, there won't be anything in there to be worried about.

- /u/socat2me 16th October, 2022 - 07:10 Try looking for calcium hydroxide instead if you really can't find sodium hydroxide (it's not on amazon or ebay?). It's used for pickling which is why it's also called pickling lime, I had great results using it and doing a straight to base method, and since it's not as water soluble you can create sort of a mud-like textured substance (I'm assuming you're working with powdered root bark). I was able to use the method where you create a bunch of mason jars and after a week or so just take off the organic layer. Except I just used a huge metal pot with a folded hand towel to set all the mason jars in and then heat water around them to speed up the reaction and do it in a day. Didn't even need a separatory funnel. Just pour off the nonpolar layer after an hour or so of heating and then freeze precipitate (if you don't have naptha forget about the freeze precipitation it isn't going to work. You're going to have to evaporate your solvent, and then if you end up with a oil/resin ubstance keep dissolving it in acetone and re-evaporating the acetone and you'll end up with a powder eventually. ). This was almost 10 years ago now though so I can't remember the exact procedure I used. Lighter fluid has more long chain heavy hydrocarbons than naphta it will be a bitch to evaporate. Camping fuel like coleman camp fuel isn't available in England? If you know any people who do fire performance like poi and shit see what they mix with paraffin to make their fuel. Check if there's an equivalent of coleman, but if not coleman, do an evaporation test first and make sure that it doesn't leave behind any additives. If you can't find any of those you need some other nonpolar solvent. Try and use ebay to check for hexane or petroleum ether although I doubt you'll find it if you can't find naphta. Look for toluene. If that fails too absolute worst case scenario use Xylene or MEK.
