METHOD OF PRODUCING ZINC ACETATE DIHYDRATE

摘要

FIELD: chemistry.SUBSTANCE: invention relates to a method of producing zinc acetate dihydrate. The method is realised by dissolving powdered zinc oxide or zinc hydroxide in aqueous acetic acid solution with ratio of reactants - zinc oxide (zinc hydroxide):water:acetic acid equal to 1:(1.6-2.0):(1.8-2.2) by weight; the obtained solution is then evaporated to oversaturation, gradually cooled to 0-5°C and held for 15-20 hours. The crystalline hydrate of zinc acetate precipitated from the solution is filtered and dried at 30-40°C.EFFECT: improved method of producing zinc acetate dihydrate.3 ex
