Abstract

1505921 Oxyhydrochlorination B F GOODRICH CO 23 May 1975 [22 July 1974 19 Feb 1975] 22527/75 Heading C2C Chlorinated derivatives of ethylene are produced by oxyhydrochlorination of ethylene or a chlorinated ethylene derivative; separating in a stream from the process any unwanted chlorinated ethylene derivatives and other byproducts; injecting the stream into a fluidized bed of a silica combustion catalyst, having a surface area of # 10 sq.m./g. and being non- friable and resistant to attrition, which is fluidized by O 2 -containing gas containing # 2 moles of O 2 per mole of C in the stream and maintained under atmospheric or superatmospheric pressure and at 350-550‹ C. to produce a mixture of hot combustion gases comprising HCl and being substantially free of Cl 2 and chlorohydrocarbon materials; and recycling the mixture of gases to the oxyhydrochlorination step. The catalyst is preferably kept at 400- 500‹ C. and a pressure of 25-150 p.s.i.g. used. The catalyst preferably has a surface area of especially 175-600 m<SP>2</SP>/g. The process is particularly suitable in the production of vinyl chloride.
