Zinc acetate is a salt with the formula Zn(CH3CO2)2, which commonly occurs as the dihydrate Zn(CH3CO2)2·2H2O. ... Zinc acetates are prepared by the action of acetic acid on zinc carbonate or zinc metal. When used as a food additive, it has the E number E650.

Application

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
