1. Main access routes

The main industrial routes to trichloroethylene from ethylene and acetylene are summarized in figure 1 .

In the main industrial processes used, trichloroethylene is co-produced with perchloroethylene.

1.1 TRI/PER process from PPG (Pittsburgh Plate Glass Co.)

Process principle

Trichloroethylene and perchloroethylene are co-produced in an oxychlorination reactor from 1,2-dichloroethane and chlorine over a fluid-bed catalyst based on potassium chloride and cupric chloride: $2 C_{2} H_{4} {Cl}_{2} + 3 / 2 {Cl}_{2} + 7 / 4 O_{2} \overset{}{\to} C_{2} {HCl}_{3} + C_{2} {Cl}_{4} + 7 / 2 H_{2} O$
