Abstract
The application discloses a process for preparing chloroethylene carbonate in an aqueous phase and belongs to the technical field of organic synthesis. The process comprises an aqueous phase chloro synthesis of chloroethylene carbonate, hydrogenation reduction and a separation and purification method. The aqueous phase chloro synthesis of chloroethylene carbonate is based on the characteristics that ethylene carbonate is soluble in water while chloroethylene carbonate is insoluble in water, chloro reaction of ethylene carbonate in an aqueous phase, separation of chloroethylene carbonate and dichloroethylene carbonate through liquid separation, the hydrogenation reduction reaction is based on the reduction reaction of dichloroethylene carbonate to obtain chloroethylene carbonate, separation of chloroethylene carbonate containing a catalyst and flash evaporation to obtain high-purity chloroethylene carbonate. The chloroethylene carbonate obtained by the application has low cost, high product yield and high quality.
