Mephedrone (4MMC) crystallization

[G.Patton]

Hello, depends on what do you need (large crystals or small ones)

Hello, what is the best way to obtain large crystals, if the crystallization time would be a maximum of 7 days?

 

[G.Patton]

Hi. You have to carry out recrystallization and cool a salt solution down as slower as possible without shaking a crystallization dish.

 

[SonicNL]

Thanks. What method would you prefer to use in this case? IPA/water 50/50 good at +- 18 C?

 

[G.Patton]

Like this, yes

An interesting cabinet

 

[ChemDamn]

hermetic cabinet, the seams are smeared with sealant, extractor hood, dehumidifier. allows you to maintain a constant temperature and humidity for the isothermal crystallization method

 

[subzero013]

I read his article about this particular cabinet. it's a pity that he stopped publishing his articles, the most interesting ones and did not come out.

Hi, I have a few questions about your method:
1) What kind of water did you use in this method (distilled, flowing, minimal, bottled),
2) At what temperature the solution was boiled
3) At what point the powder is added, all at once or in certain portions
4) During boiling, stir the solution or leave it alone
5) After boiling, the solution was poured into a crystallization container?

Well-cleaned powder, low dissolving temp and this is what it looks like after standing motionless at room temperature for 18h

 

[subzero013]

What solvent did you use? water or mixture?

 

[Chemix-Express]

Per 1g of 4mmc 1.5ml of water, heated until everything dissolved. After cooling added another 0.5ml of acetone

 

[subzero013]

the smell will be due to acetone with a large bookmark very strong, but the crystals are cool)

 

[Didi]

Wodka 40% pure and Vitamin C pure and u have maximal pure crystal later wash with acetone and this all

 

[Chemix-Express]

Adding vitamin C does not make the slightest sense. The product later appears greasy

 

[Didi]

Haha ok if u say better

 

[Angry Birds Space]

The author of this crystallization technique later refused to add vitamin C during crystallization.

 

[Chemix-Express]

I am not saying that I have to be completely right.

I saw a post here on the forum by another user who mentioned an ascorbic acid supplement.

I put down some 4MMC powder from a batch and added the said vitamin C to its crystallisation.

The final crystal with vitamin C, at least in my case, made the crystal very brittle, plus it just got greasy after a few days outdoors.

Who knows, maybe I made a mistake. No less from my side this is how it looked. Regards

 

[Angry Birds Space]

I confirm your words. The addition of vitamin C leads to loss of color during storage of the product.

@G.Pattong As promised, I crystallized the way discussed here and here is the result.

I've washed the product again and i'm going to repeat the crystallization process.
