FIELD: organic synthesis.
SUBSTANCE: invention concerns an improved method for synthesis of manganese(II) succinate tetrahydrate wherein manganese(II) carbonate is portionwise added to succinic acid aqueous solution at molar ratio 1:1:4.5, respectively, under continuous stirring and, while maintaining constant temperature 60-65°C, each subsequent portion being added after complete dissolution of preceding manganese carbonate portion, after which desired product is isolated via recrystallization. Method can be used under industrial-scale conditions.
EFFECT: improved purity of product and minimum reactants used.
