Effects of temperature of reaction zone, location of 1, 2-dichloroethane charge-in, packings and superficial velocity on preparation of 1, 1, 2-trichloroethane from 1, 2-dichloroethane and chlorine were investigated. The results showed that the appropriate reaction conditions were retention of rectification section, 105-110°C in reaction zone, augmentation of superficial velocity and use of regular packing. Under the above reaction conditions, the selectivity and production rate of 1, 1, 2-trichloroethane were improved obviously.
