just hypothetically now, if someone had about one litre of water with a few grams of ephedrine freebase disolved in it, and then this someone evaporated the water to dryness under a condenser, collecting the water, would any of the ephedrine vaporise with the water or would it have to be steam distilled?
holy sheep shit!!

the ephedrine would distill over with the water - it is steam volatile!
just add HCl until the solution is slightly acidic before evaporation - Ephedrine.HCl isnt steam volatile any more!
Or Extract the water with a NP and evaporate this to get the base!
