Propylhexedrine extraction

[MeMeLoRDexe]

Hey guys, New-ish to blue light. I'm doing a propylhexedrine extraction using white vinegar and napthta. I've gotten to the point of evap. How long does it take to evap just 100ml of the propylhexedrine/vinegar solution at 250 degrees F? It's currently been going for about a half hour

Which tek? The one off DF?

It depends on what sized container you have it in and shape. 100ml in a big baking pan under a fan will dry quick. 100ml in a tall glass will take forever.

I highly suggest using room temperature with a fan over it to avoid degradation of any of the propyl. Evaporate in a large glass pan, once evaporated pour in a tiny amount of dh2o and redissolve product. Either consume liquid as is or re-evaporate in a small dish to concentrate it, preferably a bowl. This helps get any trapped acetic acid out of the crystal matrix.
