4-MMC (mephedrone) synthesis. Complete video tutorial.

[papaji]

Done with good quantity of mephedrone anyone is here to help ???
This product has burning sensation in eyes and also have burning taste in mouth anyone's here to help me to get out this rid

 

[G.Patton]

Did you do purification procedures?

 

[papaji]

Yes i did purification procedures one is from ethyl acetate which removes almost 60% impurities after that i used syringe wash of product from isopropanol but still that product have some impurities so i recrystallization from isopropanol but this product still has burning taste in mouth and whenever it's snorted by nose it burns in nose and eyes got tears i can't use acetone because of i dont have a freezer which can give temprature to-15°c so my product almost dissolves in dry acetone do you have any further solution regarding to it please suggest me brother ????

 

[papaji]

Did you get rid out of this problem if yes then how ???

 

[Venom2021]

why the filmmaker says that the efficiency of 4mmc powder is 100g + with 2b4m ?? who's lying ??

 

[G.Patton]

Hello. Can you reformulate your question clearly please?

 

[Venom2021]

with 100g 2b4m the filmmaker receives 100g +/- 4mmc not real yield 60g / 80g this is more real output 4mmc

 

[G.Patton]

You are wrong. 100g Yield of 4-MMC*HCl is ~69% from 100g 4-methylpropiophenone. It's quite good.
Probably, you meaned 2-bromo-4'-methylpropiophenone. You have to see this topic. Video will be shared there soon.

 

[Nnn]

If we hav taken 2b4m how much time taken dissolves in NMP and heating degree also.

 

[tony rider]

Where to buy N-methylpyrrolidone?
I searched for vendors on the forum but found none. Tnx

 

[Venom2021]

if you want to make a very good 4mmc, bk4dcm and methylamine for amination are enough Benzene is carcinogenic and also not necessary for synthesis. guys have nice syntheses but too much fun in them and you won't get high scores

 

[Venom2021]

Cristal what I'm get ♡

 

[rafael1985]

Maybe You put to much HCL or all ketone was not react

 

[Venom2021]

You put more hcl to pH 4or 3 is no problem you must get powder 4mmc

 

[rafael1985]

Ad
And 5 PLN must be

 

[diogenes]

What do you mean by high scores? High yield? Do you know a good source for BK4dcm? thanks

 

[Venom2021]

Yes my good friend made a lot legal bk4
I'm say form 100g bk4 you get 60g to 75g 4mmc cristal

 

[dedhy]

What can be used instead of Hydrochloric Acid 35%? Can't get more than 10%, if I'm lucky.
Also, is it possible to increase concentration of methylamine aq sol from 38% to 40%? Is 2% critical for this synthesis?

 

[Bazooka90]

How about toluen,i put 300ml per 100g of 2b4m and my final yield was 10g of 4mmc.How much time i must let 2b4m in toluen to react and how much temperature?

 

[rafael1985]

I hear with NMP it is 15 min stirring and reaction come
