Abstract

Improved industrial manufacturing process for dichloro-1,2 ethane, in which the reaction of chlorine and ethylene is conducted at a temperature of between 20 and 80ºC under the protection of light radiation, in liquid dichloro-1,2 ethane, in the presence of a Lewis catalyst and preferably ferric chloride, continuously introducing, in a first zone, all the chlorine used and only a fraction of ethylene comprised between 90 and 100 mol% of the total chlorine, and then taking the products that result. to a second zone where the other fraction of ethylene is introduced in continuous, counter-current with a flow of liquid dichloro-1,2 ethane, characterized in that the two reaction zones are homogeneous, perfectly stirred and comprised in a single reactor, and why the set of the two ethylene injections does not exceed 102 mol% of the total chlorine.
