METHOD OF PREPARING D-ELEMENT SUCCINATES

摘要

organic chemistry, more particularly pharmacology, veterinary science, medicine and food industry. SUBSTANCE: described is method of preparing d-element succinates which are biologically active substances of complex activity. Method comprises reacting sulfate of corresponding d-metal with mixture of succinic acid and sodium hydroxide at 1:2 molar ratio at 75-90 C for 20-30 min. Method makes it possible to prepare d-element succinates of high purity including Fe2+ succinate with yields of 85-94%. EFFECT: more efficient preparation method.
