CATALYTIC HYDROCHLORINATION SYSTEM AND MANUFACTURE OF VINYL CHLORIDE FROM ACETYLENE AND HYDROGEN CHLORIDE IN PRESENCE OF SAME

摘要

PURPOSE: To obtain vinyl chloride useful for a resin, etc., with a high yield and high selectivity by allowing acetylene to react with hydrogen chloride in the presence of a specified catalytic system. ;CONSTITUTION: Acetylene is allowed to react with hydrogen chloride in the presence of a catalytic system contg. one or more group VIII metal compds. selected from among palladium and platinum compds. and an amine hydrochloride of the formula (wherein R¹ and R² are each H, alkyl or aryl and R³ is alkyl or aryl) to obtain the objective vinyl chloride. The m.p. of the amine hydrochloride is preferably ≤25°C.;COPYRIGHT: (C)1993,JPO
