Oxychlorination of 1, 2-Dichloroethane and 1, 2-Dichloropropane with Carbon Tetrachloride -Catalytic Conversion of Carbon Tetrachloride into Tetrachloroethylene-

Abstract

Since thermal conversion of carbon tetrachloride into tetrachloroethylene is an endothermic reaction, it is necessary that the reaction is performed at high temperatures such as 750 °C. On the other hand, the reaction of carbon tetrachloride with 1, 2-dichloroethane in the presenc e of oxygen is an exothermic reaction and possibly proceeds at lower temperatures.
We examined the reaction of EDC or 1, 2-dichloropropane with CTC in the presence of oxygen with an oxychlorination catalyst and obtained the following results.
( 1 ) The reaction of EDC with CTC to PCE proceeded at about 400 °C over supported CuC12-KC1 catalyst.
( 2 ) DCP was also converted into PCE under the similar reaction conditions.
