VACUUM PROCESS FOR PRODUCTION OF 1,2-DICHLOROETHANE Russian patent published in 2007 - IPC C07C17/02 C07C19/45 

Abstract RU 2301793 C2

FIELD: industrial organic synthesis.

SUBSTANCE: invention relates to a process of liquid-phase chlorination of ethylene wherein reaction heat is removed by means of vaporization of reaction medium. Process is conducted at vacuum-mediated reduction of reaction medium boiling temperature below 60°C, vacuum being developed because of condensation of vapors formed in external condenser accompanied by removal of non-condensed gases by vacuum pump.

EFFECT: enhanced selectivity of process and decreased yield of by-products (higher chlorine derivatives of ethane).
