METHOD OF OBTAINING ZINC OXIDE Russian patent published in 2015 - IPC C01G9/02 C22B3/04 C22B19/00

Abstract RU 2548537 C2

FIELD: chemistry.

SUBSTANCE: invention relates to technology of obtaining zinc oxide and can be applied for obtaining zinc oxide with displaced isotopic composition. Method includes obtaining zinc hydroxide from diethylzinc, which is carried out in flow-type reactor in water or water pulp stream, containing zinc hydroxide, with consumption of diethylzinc up to 40 kg and hour with obtaining pulp, which contains zinc particles. Pulp is subjected to separation to separate it from reaction gases and re-supplied into reactor as hydrolysing agent. After pulp saturation zinc hydroxide is separated from water by settling. Zinc hydroxide is dried and decomposed to zinc oxide.

EFFECT: process safety which is achieved due to instant removal of heat and reaction products by water stream.
