Mephedrone (4MMC) crystallization

[Dxrk]

Faster way to make crystals

 

[Khaafii]

For fastest way to make crystals you need to put the solution with 4MMC into the freezer thats the fastest way to get the crystals but they will be small.

Crystallization technique on the rotary evaporator (always produces a fine fraction).

Someone has tried it ?

1 give 1 ml water for 1 g powder cook and let closed in coolbox when I open is nothing crystalize after 1 day.
This must be open or closed and wait which method is good

 

[G.Patton]

Of course it will not crystalize. You have to evaporate water. Leave your solution at room temperature and let water to evaporate

Tell me about crystallization in brine, how to separate sodium chloride or calcium chloride from Mephedron? There is no information about this in your main post.

 

[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?

 

[subzero013]

I am interested in the crystallization method at negative temperatures. Crystallization in water at a temperature of minus 8 degrees seemed interesting, only now I could not find a freezer chamber, and at a temperature of minus 10 degrees the water itself will freeze. Here is a photo of the product obtained by this method (according to the author) - http://bbzazvqcrqtki6umyxfhni37ybttt7mkbjyxn2pgllzxf2qgyd.onion/atzccw56nma-jpeg.7537/ I don’t care what size there will be crystals, the main thing is that the process takes place in the refrigerator/freezer or in a vacuum. Can you tell you something proven and effective?

There are several method with clear explanation. Do you need something else?

 

[subzero013]

no

here is a photo of the crystals at that link.

here is my result with this method. The method is quite simple and fast. but NaCl or CaCl is not needed here at all. all you need is water and 4-mmc. bring water to a boil and dissolve 4-mmc (1g per 1ml) in it. continue to boil until the surface of the solution is covered with a film. then pour the solution into a glass container with a layer of ~ 5 cm and leave it completely at rest for 10 hours. I did this at a room temperature of + 8C. after 10 hours the crystals are ready

and this is another method. dissolve 4-mmc in vodka 1g per 2.5ml. and forget about the solution for 4-5 weeks at room temperature. vodka evaporates, crystals remain in the container

 

[ChemDamn]

minus temperature is not a prerequisite. you can do the same at a temperature of + 20C. but the higher the temperature in the room, the more 4-mmc will remain in the mother liquor. at -8C almost all 4-mmc will fall out of solution. at + 20C about 70% will fall out, about 30% will remain in the water. but what prevents you from driving off the water and getting the remains of 4-mmc, and then repeating the crystallization process again?

 

[subzero013]

For 4-5 weeks it is too long, the crystal is certainly excellent. Have you tried to use a drying stove/cabinet for crystallization? It may turn out to achieve such a result, only in a shorter period of time.

the evaporation must be slow, the slower the better and bigger the crystals. when you use a blow dryer then you will get a crystal powder
