    Abstract: Production of glycerol triacetate and glycerol diacetate by reacting allyl acetate, acetic acid and molecular oxygen at elevated temperatures in liquid phase. The compounds are more particularly produced by reacting a solution of allyl acetate in acetic acid with an oxygen/inert gas-mixture at 80 DEG to 250 DEG C. and under 1 to 200 atm. abs., in the absence of catalysts.

    Abstract: 1478093 Exhaust gas catalyst HOECHST AG 27 Feb 1975 [14 March 1974] 8257/75 Heading B1E [Also in Division Cl] A supported-catalyst suitable for oxidation of carbon monoxide and hydrocarbons in I.C. engine exhaust gases consists of 0.2-10% wt, based on the weight of support of cerium in oxide form and a support which is a mixture of delta-alumina and alpha-alumina having an alkali content of up to 0.2% wt. The catalyst may be formed by compressing hydrous alumina, e.g. boehmite, or an anhydrous alumina other than alpha-alumina, e.g. delta-alumina, to form shaped bodies; calcining at 1000- 1250‹C for 10-20 hours; impregnating with a decomposable cerium salt; drying at 130- 150‹C; calcining at 200-300‹C; calcining at 450-550‹C; and calcining at 700-900‹C.
