Oxidative chlorination of hydrocarbons. Part 1. The Deacon reaction. Oxidative chlorination of saturated hydrocarbons C1 and C2

Abstract

The review paper considers main regularities of the hydrogen chloride oxidation (the Deacon reaction) and oxidative chlorination of methane and ethane. The most efficient catalysts for these processes were shown to be the copper chloride systems on various supports, which contain also chlorides of alkaline and rare-earth metals that decrease the carry-over of the active phase from the catalyst surface and increase the activity. The main kinetic and technological regularities of the oxychlorination processes were considered. The conditions that promote an increase in the yield of target products – lower chloromethanes at oxychlorination of methane and vinyl chloride at oxychlorination of ethane – were revealed. Variants of technological schemes for the oxychlorination processes were proposed.
