Meow Meow "Voss" Synthesis (4-MMC)

[dnBQByvHb8Zkawbjpx]

Legend!

Now, where do I get HBr in required quantities and concentration in the EU as a casual consumer? Is making it at home the only way? Similarly, how do I get or I purify hydrogen peroxide to 35 % when all I can get is max 10 %?

 

[animeboro]

Yo lo haría así obtenemos 4metilenopropiofenona por 100ml 150g 2b4m utilizado 750ml acetato de etilo metilamina hcl 195g/naoh 105g+agua destilada 150ml enjuagar 3 veces con agua destilada, 450 ml cada una (total 1.4 l) y ácido hbr a pH 5 si el polvo es marrón, usar agua y sal NACI, calentar todo y meterlo en el congelador a -18°, entonces todo el NaCI quitará la suciedad cristalización mmc polvo + agua del grifo o agua del grifo e ipa 1g mmc a 0,8ml de agua calentar la solución saturada ligeramente, apartar a temperatura ambiente y al día siguiente tenemos un cristal o usar 1g de polvo 0,8ml de agua del grifo y 0,2ml de ipa y hacer lo mismo que con solo agua

Hello master, I will make this synthesis soon. briefly how to prepare 40% solution using methylamine HCl and ipa?
I know the Noah way, I am a bit confused about this.

 

[Dr. MMX]

puedes comprarlo en allegro, no comprueban nada solo envían el 35%.

 

[TheVacuumGuy]

35% and 12%, seems like it's about hydrogen peroxide.. you can use 12% in all cases just change proportions. H2O2 can also easily be purified by evaporating off the water under vacuum (heat no more than 80c) . Only problem then is you don't really know the exact concentration afterwards and your hands won't like any of it on them either.
Furthermore you really should not be afraid of buying chemicals. No one will report anything suspicious, and the type or amount of substance doesn't make it suspicious. Its behavior that does (strange addresses, Po boxes, wanting to pay cash, wanting to pick it up etc).

Very nice work, What was the yield of that?

 

[William D.]

In this synthesis yield no more than 83g (edit: ~114g) by weight, but we are more data for you in crystalline form. Expect a video of synthesis where it will be more and more accessible.

 

[Dr.Etker]

Form 100g 2bromo4methylenopropiophenone u get 85g powder 80g crystal form 150g 2bromo4methylenopropiophenone u get 120g mmc.
They use no to much ethyl acetate and then no get a lot mmc is normal much people use 300ml ethyl acetate on 100g 2b4m but normal is 500 ml and then get more mmc is normal proces

 

[William D.]

Yes, it was possible to use more ethyl acetate, but "Voss" was limited in volume

 

[Dr.Etker]

Then u use biger bottel and u get more mmc simple

 

[William D.]

Mistake, new report: yield ~114g, this is quite acceptable.
Expect a videos of synthesis and crystallization.

Great topic as always, thank you very much

Hello, please, can I use 2-Bromo-4-methylpropiophenone instead of 4-methylpropiophenone?

 

[Dr.Etker]

Yes

 

[HIGGS BOSSON]

In many countries, 2-Bromo-4-methylpropiophenone is prohibited, so we have published the simplest and fastest version of mephedrone synthesis without the use of even the simplest laboratory glassware. Only affordable chemistry, everything is very simple. And those who like the finished product will already be able to develop in the culinary business - to assemble their own laboratory.

@Dr.Etker @HIGGS BOSSON
Thank you very much for your answers. I have some chemicals left over from a failed 4MMC synthesis using DCM. I only have 2B4MP so I was wondering if I can use the rest and try to make 4MMC using this method.
