Meow Meow "Voss" Synthesis (4-MMC)

[animeboro]

Hello sir how much finish product you get this way?
How looks like finish product ?
Why u dont use freezer to get finish product ??
Why you wash freebase only one time no 3time water and water and baking soda ?
Why acid hbr ??

 

[William D.]

In addition, acidification with HBr possible without the use of litmus strips, everything is easily controlled visually when the acids become enough. This can be seen when adding drops, how it reacts. Do you get a powder at once or a red cloud. Then you need to stop adding acid.

All problems due to hydrolysis during overheating

What is temp range i need to perform good hydrolysis?

 

[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]

I would do it like this we get 4methylenopropiophenone per 100ml 150g 2b4m used 750ml ethyl acetate methylamine hcl 195g/naoh 105g+distilled water 150ml rinse 3 times with distilled water, 450 ml each (total 1.4 l) and hbr acid to pH 5 if the powder is brown, use water and NACI salt, heat the whole thing and put it in the freezer at -18°, then the whole NaCI will remove the dirt crystallization mmc powder + tap water or tap water and ipa 1g mmc to 0.8ml of water heat the saturated solution slightly, set aside at room temperature and the next day we have a crystal or use 1g of powder 0.8ml tap water and 0.2ml ipa and do the same as with just water

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]

you can buy it on allegro, they dont check anythinfg they just send 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).

 

[abis777]

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.

 

[NovicechemistEU]

Great topic as always, thank you very much

 

[qTb2c]

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.

 

[qTb2c]

@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.

 

[Toddler]

my qus after acidification with hbr 48%, ph level is 5.3(digial ph meter).

Which layer put i fridge ?

(in my case after acidification hbr 48%, i get two layers. Lower layer is aq. Top layer is oil )

Which layer i need put into fridge ?
and how temp fridge set ?
