4-MMC (mephedrone) synthesis. Bromination in dichlormethane.

[Dxrk]

Hello guys. Can you guys please give a list of reagents with proportions and a list of necessary equipment. Thanks.

Much too much. Maximum 0,430 ml 37% HCL, better even 0,415 ml of 37% of HCL, cristals will be more transparent ...

Hello everyone,i have missed to stay in 5.5ph level.by mistake i adeed more hcl and the ph now is 2.can someone tell how to rise the ph.
thanks im advance.

 

[kinshasa99]

Give what bro?

 

[CristalKing]

In my opinion ph2-3 is perfect. Product has a little to much acid but product will be more white, If ph will be about 5-6 product could be more brown.

Sorry, I mean 430 g, not ml

So if i understand well,no need for a heating plate if you use DCM?You need only to put 2br4m ,dcm and methyl in a bottle and shake it every 10 mimutes and the bottle must stay in a water bath?sound very interesting...
Ho do you control the temperature?

 

[hazel]

In water he control temperature

 

[kinshasa99]

there is no presure in the botle if is closed for 2h?

Somebody try make old method when for 1 kg 2b4m You give only 750 methyalmine in water 40% ?I know o e guy he give only this portion methylamine and reaction work normal with good yield.Why people give 2 l methylamine or more

How clean is the mmc bro then it is a chemist you didn't make ReplyReport •••

Won't the dcm dissolve the HDPE?

 

[Netflix]

No

Hello, you could not tell me regarding one moment in the synthesis. I spend sourness under the water layer, to the free base in the DCM I add water and hydrochloric acid, then I separate the water layer with the hydrochloride of Mephedron dissolved in it and work with it further. The water layer with hydrochloride dissolved in it is transparent, but has a yellow tint and has an smell of acid, even after 3 multiple of the DCM. How can such an aqueous solution be cleaned? The smell of acid appears due to an excess of HCL, this is obvious, you can fight this amount of acid, but how to remove the yellow color? Acid alkaline extraction? If it can be used in this case, then tell me the proportion and which alkali is better to use?

Hello, sorry, I don't understand you. You can push "Reply" on quotation and ask clearly.
You can add NaHCO3 no get 6-6.5 pH

If you want to make A/B extraction, you can use any alkali (NaOH or KOH).
