AN IMPROVED PROCESS FOR THE PRODUCTION OF VINYL CHLORIDE BY THERMAL ELIMINATION OF HYDROGEN CHLORIDE FROM 1,2-DICHLORO ETHANE

摘要

Gaseous 1,2-dichloroethane which has been produced in a variety of ways is heated indirectly by the hot, vinyl chloride-containing gases which are led away from the radiation zone of the pyrolysis furnace. This allows the heat of the pyrolysis gases to be utilised in a favourable manner, pyrolysis rates to be increased, and operation times of the pyrolysis furnace to be prolonged.
