Step 2 - Producing Vinyl Chloride Monomer (VCM) The ethylene dichloride is then decomposed by heating in a high temperature furnace or reactor. C2H4Cl2 = C2H3Cl + HCl ethylene dichloride = vinyl chloride monomer + hydrogen chloride. The hydrogen chloride is reacted with more ethylene in the presence of oxygen (a reaction known as oxychlorination).
