Cristalización de la mefedrona (4MMC)

[G.Patton]

El producto recristalizado es más puro y, por tanto, más potente. Además, se obtienen cristales grandes y bonitos, que resultan muy atractivos para los consumidores.

How can we get large crystal chunks like this from 4mmc hcl powder.. is this in fridge,freezer

 

[G.Patton]

¿Por qué es necesario utilizar este extraño método? Parece sucio e ineficaz. ¿Quizá pueda ayudarle con un consejo? ¿Qué quiere hacer?

 

[whitelabel]

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.

 

[Dr. MMX]

I believe that if powder required rinsing with acetone to get rid of unwanted, they could potentiall grow "harder" later on. I cant say its confirmed but its very wierd that exactly 3 cases were like that and otherwise its instantly crushing

Me interesa el método de cristalización a temperaturas negativas. La cristalización en agua a una temperatura de menos 8 grados parecía interesante, sólo que ahora no he podido encontrar una cámara de congelación, y a una temperatura de menos 10 grados el agua misma se congelará. Aquí está una foto del producto obtenido por este método (según el autor) - http://bbzazvqcrqtki6umyxfhni37ybttt7mkbjyxn2pgllzxf2qgyd.onion/atzccw56nma-jpeg.7537/ No me importa qué tamaño habrá cristales, lo principal es que el proceso se lleva a cabo en el refrigerador / congelador o en el vacío. ¿Se puede decir algo probado y eficaz?

Water will also freeze along with 4mmc..how is water seperated

 

[TheVacuumGuy]

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

 

[Yogi]

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?

 

[William Dampier]

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.

 

[SunDay]

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

 

[Dr. MMX]

Then simply dissolve the solution in the saturated solution of h2o( they are alredy purified once) and perform gradual crystalisation.
You can use the method which will grow them "more attractive" but it takes 1-3 weeks. You can heat solution to 80c and gradually decrashe it to the minimum but do use 3 ml of h2o per 1 g of 4mmc, they will probably grow bigger.

 

[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 Dampier]

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 Dampier]

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).

 

[andy.hug]

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 ?

 

[Dr. MMX]

It is estimated thats 1:1 yes.
Use the oven, heat it on 100c, when you do have oversatured solution close it and place in the oven and turn it off.

 

[Dr. MMX]

I do 1st 75% of mass 1:1, then I wait till its oversaturated to leave it in proper moment

oversaturated - the solvent reached its max temp, it cant dissolve more so it doesnt dissolve it; thin layer in the top will appear, its the moment to move it into the oven.

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.

 

[RedKing31]

What is the +- liquid hight? Pored like 5-7cm but after couple of days it’s stil like 80% liqoud on a constent tempreture of 30 degrees in plastic. We pore les? Or what’s the deal it won’t crystal like such we want?

 

[kikoliko]

We would to form shiny stones like this,we are not sure about the retio of acetone and water

 

[loadingST]

Is it a brick ?

 

[kikoliko]

Yes...

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

 

[loadingST]

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

 

[Dr. MMX]

even usage of methylamine aq already does affect the reaction with the 2b4m because of the water

Excess bromine is excess bromine... In the reaction we do need exact amounts, thats why technical data of the 4mp is needed to prepare it well for the futher reaction. It does not just disappear if its overdosed.

the "cold amination"

Methylamine may be used in liquid directly, it will probably solve the problem of the water and its negative impact. I will share the result of the tests

If hbr was used a lot of things matter more than hcl was used, maybe thats why it was not noticed any difference. WIth KBr it just reacts futher more with the already put water + 2b4m and its residues

What methods can be used to remove the yellow color from the solution of methoxyephedrine and prevent it from turning yellow again during crystallization?

 

[Come on 666]

Your crystal looks very dirty. Besides acetone, what other solvents can I use to clean it?

 

[zetvasa9]

Take 1 ml of ethyl acetate per 1 g of 4-mmc and let it evaporate in a warm place. You'll be pleased with the results. You can purify the mother liquor from impurities using a regular water filter to avoid wasting acetone.
