P2P Amphetamine (leuckart method) impossibly high yield

[skanderbeg]

Keeping it as short as possible. Did the leuckart reaction for the 1203912903 time but this time I got 110% of my base as amphetamine sulphate??? It has never happened to me before. Is it possible?? I always get arount 70% of the base as sulphate? I tried it it gets me high and it smells and tastes like the real thing.

If you calculate the theoretical yield based on molar mass of amphetamine and sulfuric acid, you’ll find out that it should be possible to turn 135,21 grams (1 mole) of amphetamine into 184,25 grams (1 mole) of amphetamine sulfate (100% yield). So yes, it’s possible that you got “110% yield” from amphetamine base, or rather 81% yield, because if you turn for example 100 grams of amphetamine base into 110 grams of amphetamine sulfate than that’s not 110% yield. You have to take into account that mass isn’t the same as molar mass.
