METHOD OF HYDRODECHLORINATION OF CHLORAROMATIC COMPOUNDS AND CATALYST FOR METHOD REALISATION Russian patent published in 2008 - IPC C07C17/395 B01J23/44 A62D3/00

Abstract RU 2339606 C2

FIELD: chemistry.

SUBSTANCE: method of hydrodechlorination of chloraromatic compounds, in particular polychlorbenzoles, is realised at temperatures higher than 100°C in presence of palladium catalyst on solid carrier. Catalyst, used in method, contains palladium from 4·10^-4 to 1·10^-2 wt %, and size of not less than 90% of metal particles lies within range 2-5 nm.

EFFECT: neutralisation of toxic chloraromatic compounds in milder conditions without formation of hydration by-products; increase of catalyst productivity; simplification and cheapening of process technology.
