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/in2 (0.35 kg/cm2) to 250 lb/in2 (17.50 kg/cm2); 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.
