Abstract
1505869 Oxyhydrochlorination B F GOODRICH CO 23 May 1975 [22 July 1974] 22477/75 Heading C2C Chlorinated derivatives of ethylene are produced by oxyhydrochlorination of ethylene or a chlorinated ethylene derivative, separating in a stream from the oxyhydrochlorination process any unwanted chlorinated ethylene derivatives and other by-products; injecting the stream into a fluidized bed of Al 2 O 3 -SiO 2 combustion catalyst comprised of 13-94% by weight of Al 2 O 3 and 87-6% by weight of SiO 2 , 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 at least 2 moles of O 2 per mole of C in the stream and maintained under 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 oxyhydro-chlorination step. The catalyst is preferably heated to 400-500 C. and kept at 40-100 p.s.i.g. A contact time of 5-50 seconds is suitable. The process is suitable for the production of vinyl chloride.
