METHOD OF TREATING ORGANCHLORINE WASTES CONTAINING CARBON TETRACHLORIDE Russian patent published in 2013 - IPC C07C19/43 C07C21/12 C07C17/269 C07C53/06 C07C51/00 C07C19/41

Abstract RU 2478089 C1

FIELD: chemistry.

SUBSTANCE: invention relates to a method of treating organochlorine wastes containing carbon tetrachloride by liquid-phase hydrodechlorination thereof with hydrogen on a palladium catalyst on sibunite. The method is characterised by that the process is carried out in the presence of a solution of sodium hydroxide in water at temperature of 100-120°C and pressure of 0.3-2.0 MPa.

EFFECT: use of the present method increases service life of the catalyst.
