发明名称 METHOD OF PRODUCING ANHYDROUS STRONTIUM FORMATE
摘要 FIELD: chemistry.SUBSTANCE: method of producing anhydrous strontium formate is carried out by reacting formic acid and crystalline strontium carbonate. The method includes boiling off the reaction mass and drying the separated end product. Strontium carbonate is added to 12-14% aqueous formic acid solution in portions at a rate of 10-50 g/min with an interval of 10-30 min between portions at 25-40°C, wherein formic acid is used in 10-20% excess of the stoichiometric amount, and after adding strontium carbonate the reaction mass is boiled off, cooled while stirring, followed by filtering out the precipitated crystals which are washed with saturated aqueous strontium formate solution which is purified in advance, pressed and dried at 130-150°C.EFFECT: obtaining highly pure anhydrous strontium formate and an advanced method for production thereof.3 ex
