Abstract
PURPOSE: To facilitate the elimination of the heat of reaction, and to improve the selectivity and conversion ratio, by circulating part of the condensate of the reaction product, in the vapor phase, in the presence of a liquid phase, in obtaining the title compound by the photochemical reaction of 1,1-dichloroethane with chlorine.
CONSTITUTION: The reaction mixture obtained by the reaction of 1,1-dichloroethane with chlorine from the photochlorination reactor, is cooled to 70°C or below. The condensate in an amount of 0.2W20mol based on one mole of the 1,1-dichloroethane and chlorine in total, is circulated, and the reaction is carried out in the presence of a liquid phase, preferably with a small amount of iodine or its compound, in the vapor phase at 50W150°C. Coexistence with a liquid phase may suppress the increase in the heat of reaction and improve the supply rate of the chlorine.
