METHOD AND DEVICE FOR PRODUCING 1,2-DICHLOROETHANE THROUGH DIRECT CHLORINATION Russian patent published in 2010 - IPC C07C17/02 C07C19/45 B01J8/22 B01J10/00 

FIELD: chemistry.

SUBSTANCE: invention relates to method of producing high purity 1,2-dichloroethane from dissolved chlorine and dissolved ethylene which are brought into contact with each other while using a liquid reaction medium excited for circulation, where the said medium essentially consists of 1,2-dichloroethane and a catalyst and at least passes through a vertical reaction zone which forms a loop, where both knees of the loop are joined by a gas separator lying above, from which the reaction product is tapped in gaseous and/or liquid form, characterised by that: at least 3 supply sections are located in the knee of the loop along which the liquid flows upwards; and each of these supply sections consists of a unit for supplying dissolved or gaseous ethylene located at the inlet of the section, and a unit for supplying dissolved chlorine located at the output of the section, and can also have static mixing devices. The invention also relates to a device for implementing the said method.

EFFECT: method is more cost-effective, enables increase of power without increasing outside dimensions of the reactor and simultaneous production of high purity dichloroethane.
