    • PURPOSE: A method for preparing ethylene dichloride is provided to effectively suppress by-products by processing parameters, to improve selectivity of ethylene dichloride, and to effectively synthesize ethylene dichloride. CONSTITUTION: A method for preparing ethylene dichloride comprises a step of synthesizing ethylene dichloride through the reaction of ethylene and chlorine in an ethylene dichloride solvent. The purity of the ethylene dichloride solvent is 85~99.8%. The rate of the ethylene/chlorine is 1.0~1.2. The reaction temperature is 100~ 125 °C. More preferably, the purity of the ethylene dichloride solvent is 90~99.8%, the rate of the ethylene/chlorine is 1.05~1.15, and the reaction temperature is 110~120 °C.
