Rekristallisation von Methamphetamin

[fajkar]

Einen schönen Tag noch, Sir. Gibt es wirklich keine andere Möglichkeit, große Kristalle schneller zu bekommen, als 1,5 Monate zu warten? Ich habe alle Möglichkeiten ausprobiert, aber es will nicht klappen, bitte helfen Sie mir.

Hello sir, is there a method to rapidly crystallize racemic compounds? Crystal size doesn't matter

You can evaporate the acidified solution to obtain the powder immediately.

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.

Yes it can, this is a great way to achieve a good yield and it's shown for example in this video. I can't comment on the time, just the general principle.

I assume that your meth free base will be partially overoxedized by HCl gas and you can get spoiled product.
