Abstract
A method for producing dichloroethane (EDC) by reacting ethylene and chlorine in a liquid reaction medium composed mainly of EDC at a temperature of not less than the boiling point of EDC measured at ordinary pressure, characterized by leading the vapor of the reaction medium generated in a reactor from the top of the reactor to a heat exchanger so as to recover and utilize the latent heat resulting from condensation of the vapor in the heat exchanger. According to the present invention, high heat utilization efficiency can be attained with advantages as compared with conventional EDC production methods.
