Reaction scheme: Reagents: 2-Bromo-4'-methylpropiophenone (cas 1451-82-7) - 5 kg; n-Methyl-2-pyrrolidone (NMP; cas 872-50-4) - 20 L; Methyl amine 40% aq. solution (cas 74-89-5) - 8 L; Benzene - 20 L; Acetone - 30 L; Hydrochloric acid con. aq. solution (HCl 36%) ~ 1.5 L; Distilled water - 20...

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 <60%; Well-ventilated room (with air...

Reaction scheme: Reagents: 4'-Methylpropiophenone (cas 5337-93-9) 5 kg; Сooper(II) oxide (CuO) 2.7 kg; Isopropyl alcohol (IPA) 50 l; Iodine 6.5 kg; Equipment and glassware: 100 L Batch reactor, which is equipped with drip funnel, top stirrer, thermometer, temperature control system...

Introduction Mephedrone (4-MMC) synthesis reaction is carried out with production of some amount by-products. Also, some amount of unredacted precursor is left in the reaction mixture after reaction. It takes to purify a 4-MMC product with insufficient purity to reduce health risks. Manual As...

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...
