Yo . I came up with another idea how to build a synthesis device ... (for mephedrone synthesis in nmp) thanks to the gravitational flow of the liquid we are able to divide the solution after the reaction (right after the methylamination is finished). Thanks to this, in tanks of this capacity...

Hello, I have an idea to build such a tank for mephedrone synthesis .. what do you think, can you advise something, what to change? hardware description: conical tank 115l. attach the stirrer to the top cover, make a hole for an additional substance inlet, install a reflux condenser and a...

This video represent a simple synthesis way of 4-MMC (mephedrone) in a small scale from 4'-methylpropiophenone. There is total synthesis video manual which explain everything and gives opportunity to make 4-MMC to every beginner of organic synthesis. Equipment and glassware: Round bottom...

Reaction scheme: Reagents: 4′-Methylpropiophenone (cas 5337-93-9) 1000 g; Hydrobromic acid 48% aq. 1140 g or 765 ml; Hydrogen peroxide (H2O2) 35% 328 g or 290 ml; Sodium bicarbonate (NaHCO3); Distilled water; Equipment and glassware: Three necked round bottom flask 5 L; Retort stand and...

4-Methyl-N-methylcathinone is a powerful synthetic stimulant drug and cheap euphoretic. Importantly, it is most demanded and wide common. It is known that big number of drugs on dark market are sold without purification (with enormous number of side synthesis substances). Using of these drugs...

4-Methylmethcathinone crystallization conditions: - Constant temperature 22-24 ºC; - Dry air (<40% relative humidity); - Container volume; Simple method Isopropyl alcohol (IPA) or ethanol solution with water is prepared in ratio 30/70, 50/50, 70/30. Proportions are adjusted according with a...

The most abundant impurities in commercial mephedrone are used to be precursors (methylamine hydrochloride, haloketones) and isomerization products (iso-mephedrone and pyrazines). These substances are toxic. The aim of this article is to learn how to quickly identify certain impurities in the...
