In reference to Placebo's RP/I reduction of ephedrine meth synthesis, meth freebase oil in toluene, will be crystallized by adding distilled water, and acidifying with hcl/muriatic acid until PH is 7. This way you don't have to run hcl gas through the toluene, although it is more tedious and you have to shake,test,add more HCL until you reach the right PH, and you have to be more careful evaporating the water so you don't lose some crystals.
My question is whether this same method will work for getting MDMA crystals. In methylman's reductive amination of MDP2P with nitromethane and Al/Hg, he seperates the water/sludge layer from the MDMA oil layer using toluene. The synthesis calls for anhydrous conditions, and since my chem knowledge is very limited, I am not sure if adding a little bit of distilled water, and acidifying with HCl, and evaporating the water to get MDMA crystals would work?
All inputs are greatly appreciated.
