Metamfetamin átkristályosítása

[fajkar]

Szép napot kívánok, uram! Tényleg nincs más módja annak, hogy gyorsabban jusson nagy kristályokhoz, mint másfél hónap várakozás? Már minden módszert kipróbáltam, de nem akar működni. kérem, segítsen nekem.

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.
