Hi there! A friend wanted to know how to purify coke hcl without distillation or dry bubbling of acids.... I did a search, but found nothing specific, and I've never tried it, so maybe someone could help him....
Please comment:
I would think a regular a/b extraction would work -- basify w/ NaOH, dissolve in ether, evaporate to yield the freebase then dissolve the freebase in water by adding just enough HCl to the water to react with the freebase. Would crack dissolve (by reacting w/ the amine) in the acidic solution, or does heat need to be applied? I'm assuming once it's dissolved in the water it should be the salt, so the person could just evap the water and be left with the hcl salt?
Thanx,
