FIELD: production of potassium succinate useful in pharmacology, veterinary, medicine as drug or bioactive additive.
SUBSTANCE: potassium succinate in obtained by reaction of calcium chloride solution with reactive mixture of succinic acid and sodium hydroxide in molar ratio of 1:2, respectively at 20-30°C. Calcium chloride solution is added for 2 h followed by mixture conditioning for 3 h for crystallization finishing. Precipitate is separated, washed on filter and dried at 100°C for 12 hours. Target product is obtained in form of monohydrate.
EFFECT: accelerated method with reduced energy consumption.
