Hello everyone. I tried to make some amphetamine using this recipe on a small scale, but failed. Everything seemed ok, after drying my product looked like white powder with a tinge of redness. If it was amphetamine sulfate (which I was trying to make), the yield would be 84%. The problem is, it's not amphetamine.
Physiological effects
I tried 20-30 mg, there was definitely stimulation, but also it caused fever and, apparently, a decline in immunity: both times I took it for several days in a row, I fell ill with respiratory infections (first time I thought it was a coincidence). Another person that took it did not experience any stimulation from up to 90 mg, only some mouth dryness. Neither of us have any tolerance to stimulants.
Chemical testing
1 g of the powder completely dissolves in 10 ml H2O.
When I added excess NaOH solution to a measured mass of the powder in a test tube, I got an approximately right volume of freebase smelling of ammonia. I separated the freebase layer, dried it with CaCl2 and tried to titrate it with acid. As a result, I measured molar mass of the freebase to be about 171 (and for amphetamine it's 135). While my measurements weren't very precise, the difference is still too large to be explained by measurement errors alone.
My deviations from the procedure
1) When adding P2NP, I realized it was going to take hours, so I got impatient and immersed the reaction flask in a room temperature water bath. After that I was able to add P2NP almost all at once, and the temperature of the mixture didn't exceed 40-50 °С.
2) I was following the video, so I didn't evaporate the IPA and added conc. sulfuric acid to the IPA/freebase layer directly.
3) I didn't have any acetone at the moment, so I didn't add it before acidifying and I washed the filtered "amphetamine sulfate" paste with IPA.
4) IPA is less volatile than acetone, so I had to put my precipitate in an oven for several hours to dry it to constant weight. The temperature in the oven didn't exceed 80 °С.
So, the big question is, where did it go wrong? I wouldn't be surprised with low yield or no product at all, but getting a good yield of an amine that's not amphetamine?!
