To quote Newton from [url=Post 501322 (missing)
(place: "Fucked up recrystallization?", Stimulants):
20g of l-ephed.hcl will not completely dissolve in 1/2 litre of warm IPA.
There must be a more efficient alcohol than IPA when playing with l-E.
From various posts i've read that EtOH was reported to give better results than MeOH and IPA.
Both yieldwise and in respect of pulling out less gak/fillers. As MeOH is hard to get and and e.hcl
is less solluble in IPA, perhaps denaturated is the way to go. In swims location denaturated is pure ethanol
with denaturating and color agants. I.e. No MeOH.
It has also been brought to my attension that the EU pills are infact gaked in the same manner as US pills.
This was not the case a couple of years ago he said.
This statement comes from someone with hands on experience with EU pills.
I also talked to another bee that did a water pull and A/B it. Hoping for a writeup from him.
Here are some refs for ephedrine.hcl (it varies from psuedo as you probably know):
