Special capillary column for the determination of preparation products of monochloroethylene carbonate
Special capillary column for the determination of preparation products of monochloroethylene carbonate Details:

Name: capillary column

Specifications: 30m*0.32mm

Model: HH-CEC



The preparation method of monochloroethylene carbonate comprises: in a tower reactor, along the direction of tower height, every 1 meter is a packing layer, installing a bracket, and installing a first mercury immersion lamp at the bottom of each bracket, Above each layer of packing, install a liquid distributor and a second mercury immersion lamp respectively; preheat ethylene carbonate to 60°C, add initiator and catalyst, and heat to 60°C to obtain a mixture containing initiator and The ethylene carbonate liquid of the catalyst; nitrogen is introduced from the bottom of the tower to replace the air in the tower, and the nitrogen tail gas is vented; after the chlorine gas is dried and dehydrated, it is heated to 65 ° C, and chlorine gas is introduced into the bottom of the tower and the middle of the tower respectively. agents and catalysis.

Haohan Chromatography (Shandong) Application Technology Development Co., Ltd., keeping pace with the times and guided by the scientific development concept, has developed and produced a special gas chromatography GC- for the determination of the preparation process of chloroethylene carbonate. The content of dichloroethylene carbonate and the remaining raw material ethylene carbonate, high column efficiency, good separation, and symmetrical peak shape. This technology is unique in the vast chromatography.
Among them, the raw material ethylene carbonate (EC): 5.7062%; dichloroethylene carbonate (DCEC): 9.46%; chloroethylene carbonate (CEC): 81.14%.
