METHOD OF PRODUCING ZINC PEROXIDE Russian patent published in 2012 - IPC C01G9/00 C01B15/47 

FIELD: chemistry.

SUBSTANCE: invention relates to chemical engineering. The method of producing zinc peroxide involves reaction of zinc oxide and hydrogen peroxide, followed by dehydration of the reaction product. Components react in molar ratio zinc oxide/hydrogen peroxide ZnO/H₂O₂=1.0-0.85, and temperature in the synthesis zone of 15-30°C. When mixing the starting components, zinc oxide is added to hydrogen peroxide which is first stabilised with magnesium sulphate in molar ratio hydrogen peroxide/magnesium sulphate H₂O₂/MgSO₄=700-850. Dehydration of the filtered reaction product is carried out by exposure to microwave radiation.

EFFECT: invention increases content of the basic substance in the obtained product and reduces power consumption.
