1535584 Palladium acyloxylation catalyst HOECHST AG 4 March 1976 [4 March 1975] 08687/76 Heading BIE [Also in Division C2] A palladium catalyst, suitable for the oxacylation of olefines in the gaseous phase, is prepared by impregnating a catalyst carrier with a solution of a palladium compound in an unsubstituted monocarboxylic saturated aliphatic acid other than formic acid, drying the catalyst at less than 90‹C until the residual solvent content is no more than 8% by wt., and reducing it by passing a gas mixture comprising an inert gas and a reducing agent over the catalyst. The use of acetic acid to prepare Pd on silicic acid and active charcoal catalysts, including Cd, K, Mn, Au, Ba, V and Bi is exemplified. |
