4MMC/MEC large crystals

[Spindy122]

I’m trying to find a decent method for large crystals. I’ve been heating the saturated solution to boiling then wrapping in a sleeping bag overnight to obtain them.

Problem is that I’m sure the heating to 100deg (the solvent is 100% water) is damaging the product and creating impurities. Would this be correct?

I have grown single crystals around 5mm thick, 10mm wide and 30mm long using this method but I feel it’s wasteful and inefficient.

Any ideas?

Also, I’ve recently synthesised 4MEC. When I tried synthesising 4EC it turned to shit real quick, extremely hard to crystallise. I accidentally synthesised 4M*C once which what I think was triethylamine and it crystallised very easily into blocks, not really active though. Would I be right is saying the longer the molecule, the easier it crystallises? I say this because Methcathinone is impossible to crystallise, and methylone is simple. Should 4MEC be easier than 4MMC?

A single 100ºC heating will definitely not damage your 4mmc.
Crystallization process conditions and parameters can be carefully selected to optimize crystal dispersion. In order for the crystalline product to acquire the desired properties, it is important to understand how the process parameters affect the main transformations during crystallization - nucleation, crystal growth, and decomposition.
In addition, different substances crystallize differently and have different lattice structures.
4mmc and 4mec most often have needle-like crystals, the other is harder to extract.
Have you read my topic on mephedrone crystallization?

Thanks for the reply, sorry dual account (must have registered twice).

I’ve got a reasonably good understanding on it. I think I was making quite an impure product as I made my bromo-ketone with Cu2Br and failed to clean it up well before amination. I was also performing this second step without DMSO/NMP so yields were horrific - around 30%.

I extracted it with sulphuric acid, then turn back into a free base with sodium carbonate. After extracting that with xylene I added hydrochloric acid with water, then after separation I would boil it down over a long period which I feel may have either caused decomposition or simply concentrated the impurities along with the product.

At that point I would recrystallise the raw product with methanol, then freeze it out. Overall this reduced yield even more. My market demands a larger crystal size, the bucket in the sleeping bag works well, just wondering if there’s a more efficient method

Side note: I recently achieved 70% yeild with DMSO. Very clean. This site is a lifesaver.

Sorry, yes I have read that topic, fantastic advice thanks. I refrained from using alcohol as it made the crystal size too small.

Use acetone with water or IPA with water and add more of this solution per powder (3ml to 1g, 5ml to 1g)

 

[Acidosis]

I use THE SOME METHOD 1g of powder to 3ml iso/3ml water.

cute color :3

 

[Acidosis]

Thnx bro!!

 

[Straightshot210]

These look great. Evaporation or slow cooling?

 

[G.Patton]

Is it 4-MMC? It has to be transparent. Did you add dye?

 

[Acidosis]

Hry my slow response..this crystals no is 4mmc ,this crystals is bkmdma and is corored in the recrystalizer process

 

[G.Patton]

Looks like over-oxidized product.

Slo
Enfriamiento lento a temperatura ambiente

No only added pink color in the recrystalizer proceso bro,

This is what im get form 5kg powder 4mmc

 

[johnny.b]

What proportions You give for 1 g powder to crystalize.This last two pictures are 4 MMC to?

 

[johnny.b]

How much water You give for 1 g powder.You crystalize maybe 4 cmc

 

[fuckypu]

The do
1g 4mmc
2ml water
0,5ml alkoholu Ipa
all picture is 4mmc for me cmc is shit
