CATALYTIC SYSTEM AND METHOD OF PREPARING VINYL CHLORIDE Russian patent published in 1996 - IPC

FIELD: production of catalysts for petrochemical processes. SUBSTANCE: catalytic system for hydrochloration of acetylene to produce vinyl chloride contains VIII group metal compound and sterilely hindered amine hydrochloride with melting point as high as 25 C and having 8-35 carbon atoms and general formula R₁R₂R₃C-Nh₂•HCl wherein R₁ and R₂ are H, or, identical or different, alkyl or aryl groups; R₃ is alkyl or aryl. Concentration of VIII group metal compound is 1-200 mmole per 1 l of amine hydrochloride. Preferably, this metal compound is palladium or platinum compound, more preferably, palladium or platinum chlorides. Reaction is conducted at 80-200 C at molar hydrogen chloride to acetylene ratio (0.5-3):1. EFFECT: enhanced catalyst efficiency. 12 cl, 6 tbl
