Mephedrone (4MMC) crystallization

[G.Patton]

Why do you need to use this strange method? It looks dirty and ineffective. Probably I can help you with an advice? What do you want to do?

Any way to get brown or cream color "cakes" from 4mmc hcl not just crystals. Brown/cream color slabs or cakes about 2 to ,3 inches thick that have crystals in and around the pieces, these slabs hold their form once solidified and dried and do not crumble. I will be obliged for any knowledge regarding this 4mmc crystallization form and procedure if you have encountered such crystal slabs or cakes

 

[G.Patton]

How it's possible? Apply more force to do it. To be honest, I don't clearly understand what is a problem.

My latest crystal, from a failed batch which i put in a beaker and used as container to drip remainders of solvents, acids andsoforth. After some weeks i needed the beaker and while cleaning it, i found these.

Now i want to make these on purpose but how... without using loads of beakers as a waste bin

I never so 3cmc in flowers like crystals

Result of 150g mmc 1:1 watter. 80celcius solution, put in towels at ~24c. after 12h got ~38g crystals like these, mother liquid must be evaporated to get rest mmc. I dont know what i did, becouse second try of this method was not succesful at all. But i Want to get crystals like these any advises?

You need to understand the theoretical yield (how much acid you used) and keep the same proportions for the product, water and temperature so that the result is stable.

Okay.. Sometimes its differs, becouse I cant achieve full control of reaction(time to time its going better), but mostly for 100g bromo 40ml 28%hcl

But what does crystallization have in common with recrystallization. I already have white, no odour crystals but suggar size and want to make bigger - "like flower". today i got it again flower like. but from 80g got ~20g flowers then put to fridge and all my "flowers" now in the tiny snow flakes

 

[SunDay]

And again 1:1 watter, towels slow cooling.. and got these. clean but nor nice I want to get crystals like other time... Whats wrong guys?

 

[William D.]

This product is even more convenient to use, even if you don't like the size of the crystals.

 

[SunDay]

I agree, but sometimes I need glass like crystals. And for myself I want to do it perfect, I want to learn how to do it even I dont need it

 

[William D.]

Use hot solvent, and do not let the mixture quickly become cold. You can use less solvent and control the cooling temperature. Then you can get crystals larger and faster. But with this method and a small amount of solvent, do not use open containers (you need to avoid liquid evaporation and create pressure). These are the foundations of a faster method, but there are others (but I take more time).

How much water I must use per 1 g powder if 1:1 is to much in this method?Can I use coolbox to cooling slowly ?

Hi
What's the fastest way to get fat chunks like slabs not all crystals but hard chunkss of mephdrone cake with crystals embedded an around, from 5kg mephedrone flour. Pease someone assist wth this, God bless you guys

Something like this but more slabs

The fastest way to crash out crystal is by taking advantage of the different solubility at different temperature. Mix 1 g of 4-MMC in 1 g of water and heat until fully dissolved into a clear solution. Kill the heat and leave to cool down to room temperature undisturbed. Two layers of crystal cake (one at the bottom and one at the surface, if the depth of the solution allows) will form within few hours. Strain excess liquid and let dry until constant weight.
