PROCESSES FOR THE MANUFACTURE OF 1,2-DICHLOR-ETHANE FROM A SOURCE OF HYDROCARBONS, FOR MANUFACTURING VINYL CHLORIDE, AND POLY (VTNYL CHLORIDE). A process for the manufacture of 1,2-dichloroethane from a hydrocarbon source according to which: (a) the hydrocarbon source is cracked to produce a mixture of products containing ethylene and other constituents; b) said product mixture is separated into a fraction enriched with compounds that are lighter than ethylene, containing part of the ethylene (fraction A), an ethylene enriched fraction (fraction B) and a heavy fraction (fraction C). ); c) fraction A is converted into a chlorination reactor and fraction B into an oxychlorination reactor, in which reactors most of the ethylene present in fractions A and B is converted to 1,2-dichloroethane; (d) The 1,2-dichloroethane obtained is separated from the product streams derived from the chlorination and oxyclaration reactors.
