Mephedrone (4MMC) crystallization

[William D.]

No DCM crystallization. Only water+alcohol (vodka), water+acetone. Proportions - 1:1 - 1:3 powder:liquid. Percentange for acetone/alcohol in water depends on the quality and purity of the powder than dirtier, the more. The growth rate and size of crystals depends on the total amount of solvent

Which solvent is best in making and crystallization please tell me sir

i have a questions about crystallization of 4mmc*hbr(!! not hcl) so i used to work with scales about 15kg in one pot
my yields in bromination is 96-100% of theory, amination give me 86% of FB (it is theory almost max, you cant move further balance of reaction) and acidification with
diluted hbr in totalness to make 1g mmc to 2.5ml o water. So, even without washing i have this after acidification -

clean,needles matt like fiber glass (room temp +8) but allexcess water inside this matt, and this is problem.First time i try to melt it, place in +22c 35% humidity, and after 4 days i have this -

some are okay, some not. So the problem is something inside is oxidizing or simple condensed to trash point where it osibviously bad.
DCM is bad in washing aquos solution of 4mmc, he only wash some trash which is nonpolar. So it can help but a very little.
My question is - how to extract clean 4mmcHbr fron not so clean brine h2o.
First i thought. thay if a lot of mmc precipitated at +8c, maybe it`s much more simple in comparison with 4mmcHcl to make a cold extraction, so i try 500ml h2o +40g mmc, and place in friedge for 12h, no result, how is it?!

overall i have a few ways - try salt\acetone extraction
try to crush this glass like matt and rinse with ipa\acetone
or ...a lof of or.... So i need a man with expirience with 4mmc*Hbr (i`m a pro on hcl, but this situation is slightly different)
on all photos here - same mef in h2o, and sorry for my eng

Wow, i havent tried to make hbr cathinones, its one of my intends to try out some hbr salts too,it seems its less soluble then hcl in water ?, i usualy get donations from guys with almost exact the same peoblem but with hcl, i know how to remove yellow collor and then crystalize into transparent glass, as hbr is more bulky it makes the mass of pure product wven more, in this moment im rhinking did anyone ever tried to prepare a something with HI acid xd

 

[ghostimage]

at first i think that graph temp\so;utability is moved far right in comparison with hcl, like hlc mmc crystallise from water at ~ -18c, but now i make a test and seems that no, it`s no temp\solutability, it`s about overall solutability in water, as you say.
I know too, but i need a dessalination\freezeng parameters with precise, i need 100% yields, without any product in the trash. btw i make 4mmc for 3-4 years in scales from 15kg to 150kg in onepot, but i reach the point, than my russian\ukranian community cant effectively find solutions for this small problems,and i try bbgate cause in overall 4mmc synthesis is easy as crap, but details....details are the devil in the box)

like, for mmc*hcl you need to cool solution with 1c at hour from 25-30 to -18 if you use nacl\acetone\ethanol etc, so mmc*hcl percicipate almost fully, maybe 2% lost in solution, but for mmc*hbr no one can realy answer me

 

[ghostimage]

HI no, its toxic, the most easyiest form of salt for human biochemical is orthophosforic acid (in east europe used for soldering) cause phoshates is energy cycle of human, like ATF etc, but cons are - even less time duration, pros - weight even more than hbr and compeletely legal to buy.
damn, i even one time try to lemon acid from your local food shop, it`s works but in help with microwave owen, some funny shit the porcuct is mefedrone citrate, crystallize from gummy like squish

Haha nice to meet guys like you here, i havent done anything large never, im just a hobby chemist, for crystalization i use the slower way always i hadnt had to rush for anything, but realy you method is a lot less time consuming and a lot less smelly, im thinking as wee see on the image posted the crystals that form are this small icy crystals, like from very fast recrystalization, i think you had to try with more solvent and slower precipitating, maybe drop the temp by 1C per a few hours and absolutely no vibrations and free of trash inside(better filtered) and you shoud grow these bigger shards with hbr, i dont see a reason to dont.

 

[ghostimage]

1c per hour is a basic knowledge, problem is - you need to carefully control it, or use very large batch so it naturally will cool at a small pace, i will try it of course

Yea cobtroling the temp in the room, which reflects the temp of the solution is not so basic knowledge but if you say haha, if you have time, why dont you use ipa/water for making caths crystals, yes its slow but works very clean and makes these bog crystals users want.

 

[ghostimage]

i use ipa\water, why you think i`m not? just it`s not optimal for not clean solutions.
i`m from russian side of darknet, here is 7th grader know how to make 4mmc in bottle of cola, and a lot of things are basic knowledge, not sarcasm, btw a lot of methods here just a translation from russian, and recepies is old and considered trash now. In some methods which a read here a very bad mistaces about h2o2 amount, they calculated it as br2 instead ob just br, and no extra added, so x2 +30% on top and you have 750 ml h2o2 instead of 260 or something....

Xd i know how to calculate, 7th generation in making mephedrone aounds funny, there is just a simple machanism once you understand it it works wonders, and there is a magic trick to remove the yellow color of the solution afther dissolving meph, and whem letting it crystalize it dont become yellow

 

[ghostimage]

or you can make it clean from the start, and no any trace of yellow and no need in antioxidants
