METHOD OF RECYCLING CHLORORGANIC WASTES Russian patent published in 2015 - IPC C07C17/158 C07C21/10 C07C21/12 C08J11/16 A62D3/38 C02F1/72 C02F101/36 

Abstract RU 2560773 C2

FIELD: chemistry.

SUBSTANCE: invention relates to field of recycling chlorine-containing wastes of chemical industry productions. Method of recycling chlororganic wastes includes stages of their catalytic oxychlorination with mixture of oxygen-containing gas and hydrogen chloride and rectification of mixture of chlorohydrocarbons with release of tetrachloroethylene and trichloroethylene. Chlorohydrocarbons with boiling temperature in the range from temperature of trichloroethylene boiling to temperature of tetrachloroethylene boiling and highly boiling chlorohydrocarbons with boiling temperature higher than temperature of tetrachloroethylene boiling, obtained after rectification, are supplied for burning, products of burning are supplied to water trapping of gaseous hydrogen chloride and obtained hydrochloric acid is used at the stage of oxychlorination.

EFFECT: method is economical and environmentally friendly and makes it possible to obtain tetrachloroethylene and trichloroethylene with reduced hydrogen chloride consumption.
