Is there a reason Sulphate salts are preferred for amphetamines

Well possible that you can make the mono-phosphate in Acetone, I never said the method I described is the only one.
But for curiosity, why "much better"? In my eyes its at most a question of personal taste what method one prefers.

ease of preparation and isolation, amine phosphates are very poorly soluble in acetone, easy dry.

Your theoretical thoughts are not very interesting to me either. I spoke about practical experience, which I have conducted dozens, if not hundreds of times. It is useless to say anything to closed ears, so I will stop here.
