4-mmc turn red. Why?

[craris100]

I always do the same procedure with DCM and today i get a red product after acidification.

100g b24m
200ml Methylamine 40%
2 hours at 38-40C
And i wash the organic phase still methylamine odour is dissapeared.

When i acidify the base with HCL i get a red-brown product.

Anybody knows whats the problem here?
Thank you


The procesure i use. Here.

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

We'll consider mephedrone (4MMC) synthesis in this article. Dichloromethane (DCM) is used as a solvent. It has a low boiling point (~40 °C) and synthesis procedures take a little time. Work conditions: Air temperature 20-24 ºC; Relative humidity

i was reading the replies to the synthesis you linked, user @CristalKing said "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" so perhaps it has something to do with the pH?

hope this helps ^_^

Too much acid or you added acid too fast

Berlin777Its possible. Thank you!!
I add 300ml of acetone to the base in DCM and i add the hcl:acetone 1:3 but maybe i add too fast yes.

craris100I am helping one guy out, he done exactly same methodology I do but his stuff turned red. I saw he was adding acid acetone too fast but intentionally I didn't tell him anything so he know how fucked up stuff loks like

Its weird because is not the first i do this synthesis but today and yesterday was the first this happen. Yesterday and today i used a different 2b4m of other supplier and i was thinking is that.

Ph is no problem and bromoketon is also no problem.

Please @$!$, im not going to pay you 5000€ and nothing for this synthesis.
Stop of offering your recipe please, im trying to help to other people too.
One month trying to sell me your shit procedure every day via Telegram, please stop.
