I posted this in the chemistry discussion thread but I figured it would get more visibility if I made a new thread about it. Hoping someone with some chemistry experience can chime in here.
I have always used an HCL gas generator to precipitate my salts from freebase solution although another member on another forum suggested another method that seems much more preferable as HCL gassing is a mess and the clean up is no fun.
Extract freebase alg using xylene
drying xylene with drying agent(mgSO4)
combining equal parts of xylene/product with 99% IPA.
titrating IPA/xylene mixture to PH of 6 using 31% HCL solution
vacuum distill IPA off which should leave xylene and salt formed in flask
drying salt in a pyrex dish through evaporation then a little acetone at the end
I just wanted to verify before I try such method as it seems like a nice alternative to HCL gas.
