METHOD FOR OBTAINING POLYMERISABLE VINYL CHLORIDE 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 of pyrolysis of 1,2-dichloroethane, to a another cooling process at a temperature not more than 40 DEG C, under pressure ranging between 10 to 15 bars then in leaving it 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. |
