Catalytic hydrochlorination system and process for manufacturing vinyl chloride from acetylene and hydrogen chloride in the presence of this catalytic system

摘要

Catalytic hydrochlorination system comprising at least one amine hydrochloride and at least one group VIII metal compound chosen from the group composed of mixtures of a platinum (IV) compound with tin (II) chloride, mixtures of a platinum (II) compound with triphenylphosphine oxide and mixtures of a palladium (II) compound with triphenylphosphine. This catalytic system is suitable for preparing vinyl chloride by reaction of acetylene with hydrogen chloride.
