Abstract

1,2-DICHLOROETHANE (EDC) IS OBTAINED BY FEEDING CHLORINE AND ETHYLENE INTO CIRCULATED CATALYST-CONTAINING EDC, A PART-STREAM OF THE REACTION MIXTURE BEING FED TO A FLASH EVAPORATION, THE VAPORIZED EDC BEING SEPARATED OFF FROM MORE READILY VOLATILE COMPONENTS AND THESE BEING RECYCLED TO THE REACTION.
