METHOD OF PRODUCING HIGH-PURITY 1,2-DICHLOROETHANE THROUGH DIRECT CHLORINATION AND DEVICE FOR REALISING SAID METHOD Russian patent published in 2010 - IPC C07C17/02 C07C19/45 B01J19/00 

FIELD: chemistry.

SUBSTANCE: invention relates to a method of producing high-purity 1,2-dichloroethane from dissolved chlorine and dissolved ethylene, which are brought into contact with each other using circulating liquid of the reaction medium which essentially consists of 1,2-dichloroethane and a catalyst. The invention also relates to a device in which the reaction takes place, which has at least one vertical area made in form of a closed loop where the reaction takes place. Both elbows of the loop are connected to a reservoir lying above for predistillation, from which the reaction product in form of gas or liquid or gas and liquid comes out. The inlet for chlorine and dissolved ethylene lies on that elbow of the loop on which the liquid rises. The inlet for dissolved chlorine lies downstream after the inlet for ethylene which lies upstream. At least one inlet for liquid 1,2-dichloroethane lies after each inlet for chlorine and liquid 1,2-dichloroethane is fed with such high kinetic energy that the 1,2-dichloroethane mixes with dissolved chlorine and ethylene.

EFFECT: obtaining high-purity1,2-dichloroethane.
