Abstract

1326428 Oxychlorination process PRODUITS CHIMIQUES PECHINEY-SAINT-GOBAIN 12 Oct 1970 [13 Oct 1969] 48346/70 Heading C2C [Also in Division B1] An ethylenic hydrocarbon is selectively oxychlorinated by a process wherein the hydrocarbon is contacted, under oxychlorination reaction conditions including a temperature not exceeding 250‹ C., with a catalyst comprising (a) alumina, (b) at least one copper compound and (c) at least one yttrium and/or rare earth metal compound (rare earth metals being defined as elements having atomic numbers of from 5 7 to 71), the catalyst being further characterized in that (i) it contains no extraneously added alkali metal, (ii) yttrium and rare earth metal constitute (on an elemental basis) from 1 to 10 weight per cent of the catalyst and (iii) at least 90 weight per cent of the yttrium and rare earth metal content of the catalyst is constituted by yttrium and/or rare earth metal(s) having an atomic number of at least 62. Copper preferably constitutes (on an elemental basis) at least 5 weight per cent of the catalyst which may be prepared by a conventional procedure involving for example impregnation of alumina which preferably has a surface area of from 150 to 380 m<SP>2</SP>./g. and which may be in the form of microspheres obtained by calcining spray-dried alumina. The selective oxychlorination of ethylene to 1,2-dichloroethane (and by-product ethyl chloride) by contacting a gaseous mixture of ethylene, air and hydrogen chloride, at atmospheric pressure and a temperature of either 220‹ C. or 235‹ C., with a fluidized bed of catalyst is exemplified using various catalysts prepared from the chlorides of copper and of yttrium and/or rare earth metal(s), either singly or in admixture, the alumina being in the form of microspheres having an average diameter of 60 microns, a surface area of 340 m<SP>2</SP>./g. and a pore volume of 0À4 cm<SP>3</SP>./g. A comparative example relates to such oxychlorination using catalyst wherein the alumina is replaced by silica in the form of microspheres having an average diameter of 70 microns, a surface area of 350 m<SP>2</SP>./g. and a pore volume of 0À6 cm<SP>3</SP>./g.
