摘要: In accordance with the present invention, the process for preparing allyl chloride comprises chlorination of propylene with hydrogen chloride in an upward stream consisting of propylene, hydrogen chloride and a catalyst, i.e. manganese dioxide incorporated in a leaned manganese ore in an amount of 20 to 35% byu weight at a temperature within the range of from 300.degree. to 500.degree. C., concentration of the catalyst in the stream of 130-180 kg/m.sup.3, time of contact between propylene, hydrogen chloride and the catalyst in the stream of 0.2-0.7 sec and a volume ratio between propylene and hydrogen chloride in the stream of 1:3-5 respectively. Then the spent catalyst is separated from the reaction mixture resulting from chlorination, regenerated with oxygen at a temperature of from 500.degree. to 520.degree. C. and recycled to the chlorination process. The process according to the present invention makes it possible to achieve a yield of allyl chloride of up to 81.5 vol. % as calculated for the passed propylene, conversion of propylene of up to 98.0% at a process selectivity of from 80 to 85 vol. %. Furthermore, the process according to the present invention makes it possible to provide a wasteless production of allyl chloride.

摘要: Vinyl chloride is prepared by gas-phase chlorination of a gaseous mixture containing 5 to 50 vol. % of ethane and 50 to 95 vol. % of ethylene. The amount of chlorine supplied into the reaction zone is determined by the formula: number of chlorine moles=3m+ 0.3n, wherein m is the number of moles of ethane and n is the number of moles of ethylene. Chlorine is supplied into at 4 to 6 points of the reaction zone.The method of the present invention makes it possible to increase the yield of vinyl chloride up to 70% by weight, while reducing power consumption for the process 1.5 times as compared to the prior art methods.
