WebNov 1, 2024 · The oxychlorination of ethylene is an industrially relevant process within the manufacture of polyvinyl chloride (PVC). Although RuO 2 is the best performing catalyst for the Deacon process (4HCl + O 2 → 2H 2 O + 2Cl 2 ), experiments demonstrate a modest activity in the selective oxychlorination to vinyl chloride, favouring oxidation and ... Webprocesses: direct chlorination of certain hydrocarbons, chlorination of ethylene dichloride, and oxychlorination. The first process involves the reaction of chlorine with a hydrocarbon such as methane, ethane, propane, or propylene at high temperatures, with or without a catalyst. A chlorinated derivative of a hydrocarbon may also be used.
