Abstract

1338901 Propylene oxide B P CHEMICALS Ltd 13 Oct 1971 [30 Oct 1970] 51680/70 Heading C2C [Also in Division B1] Propylene oxide is prepared by reacting propylene and a molecular oxygen containing gas at an elevated temperature in the presence of a catalyst composition containing elemental silver together with a halide or halides of one or more metals of Group I of the Mendeleef Periodic Table in such a manner that not more than 15% of the total propylene feed is connected per pass. The percentage conversion per pass is defined as total percent C 3 H 6 conversion/recycle ratio and the recycle ratio is defined as flow rate of recycle gas/flow rate of fresh feed gas. The process may be carried out in the vapour phase by passing a gaseous mixture comprising propylene and a molecular oxygen containing gas at an elevated temperature over the catalyst composition. The gaseous reaction mixture may also contain an inert gaseous diluent e.g. helium or nitrogen. The reaction temperature may be in the range 100 to 400‹ C. and the process may be carried out up to about 20 atmos. gauge. The process may also be carried out in the liquid phase by introducing propylene into a reaction zone containing a water immiscible organic solvent carrying a solid suspension of catalyst and thereafter passing a molecular oxygen containing gas e.g. air through the solvent to oxidize the propylene.
