i did a p2np al/hg amination to amphetamine, but when i finished i ended up with an oil, i did not gas it with hcl i just added hydrochloric acid with acetone and dripped it into rm until i reached a ph of 6, ive tried evaporating it and just end up with an oil, and i want to get amph hcl. any suggestions on what to do would be appreciated?

Precipitation of an amphetamine with H2SO4 or H3PO4 give a powders.
But amphetamine with HCl solution with acidic pH (better 3-4) should be evaporated to precipitate and dried in desiccator contains NaOH

amphetamine FB has low solubility in water and can`t has high alkaline pH (in EtOH solution of AMP FB pH is ~8-8.5)
Use the Standard Amphetamine Test Strip for qualitative detect AMP

this is the sulphate



and this is the hydrochloride

Amphetamine sulfate is the best choice, so it is used more. Even in pharmaceuticals. HCl salt is very hydroscopic.

Is P2np soluble in acetone?

Very cool, I hope there are videos on the synthesis of xanthine derivatives.
