Totally BULLSHIT the last 3 posts!
And to the others:
Do you have only short memory?
We discussed this matter a long time ago several times, and the best solution ever found:
Use TOLUENE to mix with your DISTILLED freebase (3x more to 8x more) and neutralize with 33% HCl (=67% water in it!) or gas with 99% HCl GAS. An end pH of 4-3 doesn't hurt at all. You want to be sure that all freebase is converted to the chloride salt!
Then in case of the 33% HCl, boil off the water, filter crystals or just decant the toluene, in case of HCl gas just decant the Toluene (re-usable!), after all crystals precipitated,
then ALWAYS recrystalize your (wet or dried) IMPURE crystals by soluting in hot boiling ETHANOL or IPA (the minimum amount necessary to solute all crystals, these ALCOHOLS will keep all non crystallizable impurities soluted), and then add 3-4x icecold ACETONE (cold acetone also doesn't smell like hell!), let formed crystals precipitate, decant the alcohol/acetone off, wash crystals a few times with a bit fresh ACETONE, result: 99.9% pure endproduct.
(All extra HCl from the pH 4-3 overshooting when neutralizing your freebase will be soluted in your toluene, acetone, alcohol, so all these urban legends about burned lips and tongues, forget it!)
I'm not even going to look up the threads, should be common knowledge by now.
1. Use HCl gas (faster, cleaner)
2. If you can't get HCl gas , use 33% HCl. (In fact much safer from an acquisition viewpoint!)
Big ADVANTAGE: TOLUENE doesn't smell 1 km around your "secret" lab! LT/
PS: all these short step brainiacs drive me crazy, these are all wellknown labprocedures, any shortcut taken takes you a long way off from what is really possible in terms of purity and REAL yields.
Especially the idiots who tell me: but then I loose precious WEIGHT !
I hope you loose so much weight yourself that it becomes inpossible to multiply or set one step in a lab, stupid fuckers! LT/
