d-tartaric acid

D-tartaric acid, and importantly Cas (147-71-7), will preferentially precipitate D-Meth crystals. 13 g of D-tartaric acid was dissolved in 52 ml of methanol, then poured into 20 g of DL-methanol oil and stirred for 6 hours to generate diastereomers (D acid-D base salt)Crystals, (D acid-L base...

Introduction At the moment, there are many ways to synthesize dextroamphetamine. They can be divided into 3 types: biosynthesis (using biomass), direct synthesis, and synthesis of racemic (the sum of l- and d-isomers) amphetamine followed by separation of optical isomers. In our case, a...
