METHODS OF PRODUCING SALT

摘要

FIELD: chemistry.SUBSTANCE: invention relates to chemistry and specifically to a method of producing arginine bicarbonate. The method involves reaction of an arginine suspension with carbon dioxide at controlled temperature and pressure to form a solution which contains arginine and a bicarbonate anion, and separating arginine bicarbonate from the solution. The arginine suspension contains arginine in form of a free base or in form of a salt and a solvent; pressure ranges from 5 lb/in(0.35 kg/cm) to 250 lb/in(17.50 kg/cm); the arginine suspension is heated to temperature ranging from about 30°C to about 80°C and the solvent is water.EFFECT: method enables faster production of arginine bicarbonate with considerably higher concentration in the solution.16 cl, 4 ex
