METHOD OF OBTAINING VINYL CHLORIDE BY PYROLYSIS OF 1,2-DICHLOROETHANE Russian patent published in 2014 - IPC C07C21/06 C07C17/25 C10B43/14

Abstract RU 2506252 C1

FIELD: chemistry.

SUBSTANCE: invention relates to method of obtaining vinyl chloride by pyrolysis of 1,2-dichloroethane at temperature 480-520°C and pressure 15-30 atm. method is characterised by the following: 1,2-dichloroethane is supplied into process in mixture with hydrogen with molar ratio of 1,2-dichloroethane and hydrogen being equal 100:0.03-3.5.

EFFECT: application of claimed method makes it possible to increase inter-burn furnace run due to reduction of coke deposition, increase selectivity of process of vinyl chloride obtaining with preservation of initial raw material conversion.
