Abstract (en)
[origin: WO2010034397A1] The invention relates to a method and a device for producing ethylenically unsaturated halogenated hydrocarbons, especially of vinyl chloride, by thermally cracking 1,2-dichloroethane, using physical or chemical measures initiating the cracking reaction. The method and the device according to the invention allow the output obtainable using the cracking reactors of a defined size to be considerably increased. According to the method, initiating measures are used to increase the flux density through the wall of the reactor tube and at the same to increase the reactant feed rate and the heating capacity of the reaction furnace to such an extent that the conversion percentage of the reaction is not considerably increased as compared to methods not using initiating measures. In order to be able to operate the method in an economical manner even when the reaction temperature is reduced, the process parameters have to be adjusted such that the evaporation of the quantity of feedstock used is brought about to at least 50% by means of the perceptible heat content of the reaction mixture leaving the reaction zone.
