METHOD OF HYDRODECHLORINATION OF CHLORAROMATIC COMPOUNDS AND CATALYST FOR METHOD REALISATION

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 siz...

Beschreibung
Zusammenfassung:	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. ^ 7 cl, 3 tbl, 1 dwg, 9 ex
