FIELD: chemistry.
SUBSTANCE: invention relates to the technology of producing salts of carboxylic acids, particularly acetic acid, and a method of producing high-purity anhydrous zinc acetate. High-purity zinc acetate is obtained by reacting a zinc-containing compound with acetic acid, where the zinc-containing compound used is diethylzinc which is pre-diluted with an inert solvent to concentration of not more than 20 wt %. The inert solvent used is preferably undecane. The invention enables to obtain high-purity anhydrous zinc acetate in which content of 18 limited metal impurities, according to chemical spectral analysis, is equal to 5·10-5 - 5·10-6 wt %.
EFFECT: method enables to include the obtained anhydrous zinc acetate into the category of high purity substances ACS 18-4; can be used in electronics, fibre optics, atomic power and other areas of emerging technology.
