1. Diklorometan ima majhno topnost za metilhidroklorid in ga ni mogoče popolnoma raztopiti.
2. Vrenje diklorometana je razmeroma nizko, izhlapevanje pa je prehitro, da bi se tvorili veliki kristali, zato se bo pojavil le kot kristalinični prah.
3. Hidroklorid pred rekristalizacijo očistite (aceton, eter, suho in hladno).
4. Za rekristalizacijo je priporočljivo uporabiti - aceton: voda, aceton: etanol, aceton: metanol, etanol: voda, metanol: voda.
Voda lahko upočasni izhlapevanje, aceton lahko zmanjša topnost, alkohol pa lahko tvori boljše kristale.

Učiteljica, moj hidroklorid je čist. Ekstrahiral sem ga s petrol etrom in ga vdihnil v plinski vodikov klorid, nato sem ga posušil. Ali je čisti etanol v redu? Ali nam lahko poveste postopek

To je odvisno od vas. Če potrebujete kristalno obliko met.

Če imate d-izomer (z ločevanjem z vinsko kislino ali s sintezo z efedrinom).

Lahko zelo svetujem za metodo, ki sem jo prebral pri članu.

40 g D-metha
100 ml acetona
9,5 ml h20
-Vse skupaj zmešamo in segrejemo na 55°.
-Pustite, da se ohladi pri sobni temperaturi za 3h
- v hladilniku 2h
- v zamrzovalniku 2 h

Zelo enostavno, zelo hitro, hvala članu, ki ga je delil. Žal se ne spomnim imena.

yep this one is money! got it in the fridge now, best crystals ive seen yet, actually starts making shards not needles, hitting the freezer soon. Isopropyl works okay but I think this is better. I also tried denatured alc, that shit sucks dont waste your time.

Ker tega niste storili pravilno. Preprosto ste dodali topilo in ga nato izparili. To ni postopek rekristalizacije, ki je znan kot metoda čiščenja.

Asking experts
Can pure free methamphetamine be acidified to methamphetamine hydrochloride by bubbling HCI without any other solvent? If 99% ethanol is added in the normal proportion, will it take a long time to acidify 20ml of free methamphetamine to hydrochloride? I tried bubbling HCI gas for two hours and it still didn't turn into acid.

I'm not sure that it's good Idea. You meth can be oxidized by this way, I think.
I don't understand this part of question.

I mean, can introducing HCI gas into pure free methamphetamine (without any solvents and water) produce methamphetamine hydrochloride? I want to know the principle behind this. Thank you for your reply.
