Trichloroethylene - Production. 1  Prior to the early 1970s, most trichloroethylene was produced in a two-step process from acetylene. 2  The 1,1,2,2-tetrachloroethane is then dehydrochlorinated to give trichloroethylene. 3  or in the vapor phase by heating it to 300-500 Â°C on a barium chloride or calcium chloride catalyst.
