The invention relates to a method for the production of 1,2-dichloroethane, comprising the following steps: (A) feeding a feed gas flow containing an ethane into a dehydrogenation zone; dehydrogenating the ethane into ethene while obtaining a product gas flow containing ethane, ethene and minor constituents; (B) feeding the dehydrogenated product gas flow containing the ethane and ethene into a flow or several partial flows, optionally after separating the minor constituents, in one or more chlorination zones; chlorinating ethene into 1,2-dichloroethane while obtaining one or more product gas flows containing 1,2-dichloroethane, ethane and optionally other minor; obtaining 1,2-dichloroethane and one or more circuit gas flows containing ethane and recirculating the circuit gas flow(s) containing ethane to the ethane dehydrogenation.
