2. Other industrial processes

Trichloroethylene can also be obtained:

• by hydrogenolysis, on a specific catalyst, of perchloroethylene into trichloroethylene and HCl according to the reaction : ${\text{Cl}}_2\text{C}=\text{C}\text{C}{\text{l}}_2+{\text{H}}_2\stackrel{}{\to }{\text{Cl}}_2\text{C}=\text{CHCl}+\text{HCl}$

  Wacker (Germany) developed this process and then shut down its plant in 1994. As the catalyst is fairly expensive, the economic interest of such a process depends more on the market than on the cost of perchloroethylene...
