C'est génial.

Pourquoi pensez-vous que le congélateur a donné des résultats étranges lors de la cristallisation ?

À quel point pensez-vous que cette méthode peut être mise à l'échelle ?

A cause de l'eau, quand elle gèle, d'où devraient venir les cristaux ?
Le réfrigérateur normal fonctionne peut-être mais j'ai mes aliments à l'intérieur et je ne veux pas le nettoyer à chaque fois.
J'ai vraiment essayé beaucoup de méthodes pour arriver au produit final et j'ai aussi gaspillé beaucoup de solvants et de 2b3c, mais la méthode que j'ai décrite a mieux fonctionné pour moi que les autres essais.
J'ai failli être désorienté par toutes ces méthodes différentes, tous ces petits bols avec des mélanges différents se trouvaient tout autour, j'ai toujours regardé lequel se développait bien et lequel ne se développait pas.
Par exemple, quand on met de l'ipa glacée dans l'eau/poudre de cristallisation, on obtient instantanément des cristaux blancs mais ils ne sont pas clairs et juste un peu, donc il faut cristalliser à nouveau et le reste doit s'évaporer, regardez la dernière photo.
Les 3 autres photos montrent ce qui arrive au rm dans mon congélateur, il devient une masse solide qui fond à température ambiante, mais pas de cristaux.

it depends on how much material you want to dissolve and the water to alcohol ratio.

Is it possible to make 3mmc in powder ? Everyone is talking about acidification with water or acetone and then straight to dish and evaporate. But maybe it is possible to make it like 4mmc. Just putting HcL straight to washed rm and powder forming. Is it possible with 3cmc ? And how to do it with dcm ?

I tried this also. 1st time my HCL was 80% (it perfectly fits for H2O acidification in proper amount) but when only HCL, everything BURNT :)), and second time with 26-38% so drop was sticky flufy mass(then you need MUCH work to get crystals from this shit, and yeld was about 35%.
By the way, in market there is 28% HCL, it comes from latvia.. that shity HCL makes problem with acidification, purple or emerald color goes on, and really hard to achieve optimal ph. All latvian chem in shops ar shit, so dont be fooled.

Same, always had 25-30% after several washing and recrys...there are methods with more yield for sure, but my experiences were always around this amount
