Mňau mňau "Vossova" syntéza (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.

 

[Toddler]

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

Dobrý den, mistře, brzy budu provádět tuto syntézu. stručně, jak připravit 40% roztok pomocí methylaminu HCl a ipa?
Znám Noemův způsob, jsem z toho trochu zmatený.

 

[Dr. MMX]

you can buy it on allegro, they dont check anythinfg they just send 35 %

 

[TheVacuumGuy]

35 % a 12 %, zdá se, že jde o peroxid vodíku... 12 % můžete použít ve všech případech, stačí změnit poměry. H2O2 lze také snadno vyčistit odpařením vody ve vakuu (teplo ne více než 80c) . Jediný problém pak je, že potom neznáte přesnou koncentraci a ruce se vám na nich taky nebudou líbit.
Navíc se opravdu nemusíte bát kupovat chemikálie. Nikdo nic podezřelého nenahlásí a druh ani množství látky z toho podezřelou nedělá. Dělá to jeho chování (podivné adresy, poštovní schránky, chtění zaplatit v hotovosti, chtění si to vyzvednout atd.)

 

[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]

Forma 100g 2bromo4methylenopropiophenone u získáte 85g prášku 80g krystalu forma 150g 2bromo4methylenopropiophenone u získáte 120g mmc.
Nepoužívají příliš mnoho octanu ethylnatého a pak nedostanou mnoho mmc je normální mnoho lidí používá 300 ml octanu ethylnatého na 100g 2b4m, ale normální je 500 ml a pak dostanou více mmc je normální proces

 

[William D.]

Ano, bylo možné použít více ethylacetátu, ale "Voss" měl omezený objem

 

[Dr.Etker]

Pak u použijte větší bottel a u získáte více mmc jednoduchých

 

[William D.]

Chyba, nová zpráva: výtěžnost ~114 g, to je zcela přijatelné.
Očekávejte videa o syntéze a krystalizaci.

 

[NovicechemistEU]

Skvělé téma jako vždy, moc děkuji

 

[qTb2c]

Dobrý den, prosím, mohu místo 4-methylpropiofenonu použít 2-bromo-4-methylpropiofenon?

 

[Dr.Etker]

Ano

 

[HIGGS BOSSON]

V mnoha zemích je 2-brom-4-methylpropiofenon zakázán, proto jsme zveřejnili nejjednodušší a nejrychlejší verzi syntézy mefedronu bez použití i toho nejjednoduššího laboratorního skla. Pouze cenově dostupná chemie, vše je velmi jednoduché. A ti, kterým se hotový produkt zalíbí, se již budou moci rozvíjet v kulinářství - sestavit si vlastní laboratoř.

 

[qTb2c]

@Dr.Etker @HIGGS BOSSON
Děkuji vám za vaše odpovědi. Mám nějaké chemikálie, které mi zbyly z neúspěšné syntézy 4MMC pomocí DCM. Mám jen 2B4MP, tak mě zajímalo, jestli můžu použít zbytek a zkusit vyrobit 4MMC touto metodou.

 

[William D.]

You will make your task easier. Use this synthesis if it is convenient for you. Start with small quantities. Just skip the bromination step.

 

[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 ?

 

[William D.]

How much acid and for what amount was used? You need a water layer. You can crystallize it at room temperature too, only longer. And so is a regular household fridge.

 

[Toddler]

I used nearly 3ml of hbr 48%, fridge temp 1°, i reached 5.5ph,

 

[William D.]

You can add a little acid. I don’t know why, but if the litmus strip is a little red, the product is more euphoric and powerful. You can check.

 

[abis777]

interesting. What ph do you think gives the best euphoric experience?

 

[William D.]

I can't say for sure. Maybe 4 or slightly lower. Try to take one base and divide into two parts, acidify until to 6 and 4. You will understand the difference.

 

[dodobird]

Hi
I tried 5 times using exact measurements and steps but never got the whitish precipitation mentioned after adding h2o2. Seems 76ml hbr was not Enough. Would it be better to use 125 ml hbr47 instead of the 76ml mentioned? How long does the precipitaion take as per the above method? Any guesses or advise?

 

[William D.]

You can add an excess of acid now and stir it (so that the process goes faster), but do not add more peroxide.

 

[dodobird]

How long of a stir do u guess is needed once the h202 has been added and when does it go into the freezer , gor how long...guessing until the white precipitation occurs at the top layer.

 

[William D.]

Washing with pure water, if you used an excess of acid. After washing with a saturated soda solution, this will help accelerate crystallization.

 

[Toddler]

to form it takes some time and need continuous stirrer.

 

[Toddler]

Final yield

using 20g 4mpp
Yield 30 g 2b4m

 

[Toddler]

Today 300g 4mpp , 210g hbr 48%, 90g h2o2 50%

 

[William D.]

You can additionally rinse with water and a soda solution. In exactly this order. This can speed up the crystallization process if it does not happen right away. And remove excess acid.
