METHOD FOR OBTAINING VINYL CHLORIDE POLYMERIZABLE FROM A RAW PRODUCT DERIVED FROM PYROLYSIS OF 1,2-DICHLOROETHANE

摘要

The invention concerns a method for obtaining directly polymerisable vinyl chloride which consists in subjecting a cooled raw product derived from pyrolysis of 1.3-dicliloroethane, to another cooling process at temperature not more than 40 DEGREE C, under pressure ranging between 10 to 15 bars then in leaving at substantially identical temperature and pressure levels for a duration not more than 20 minutes. The invention also concerns a device for implementing the method.
