ABSTRACT:
An improved process for the production of 1,2-dichloroethane in which chlorine and ethylene are reacted in the liquid phase in the absence of light and in the presence of a Lewis acid catalyst wherein all of the chlorine used in the reaction and a fraction of the total ethylene within the range of 90 to 100 mole percent based upon the total chlorine are introduced to a first homogeneous agitated reaction zone, the products from the first zone are passed to a second homogeneous agitated reaction zone into which there is also introduced the remaining ethylene in countercurrent flow to the flow of the 1,2-dichloroethane, with the total amount of ethylene introduced not exceeding 102 mole percent of the total chlorine.
