1452145 Epoxidation catalysts SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ BV 13 Dec 1973 [15 Dec 1972] 57808/73 Heading B1E [Also in Division C2] Catalysts comprising silver on a carrier are prepared by impregnating the carrier with an aqueous solution comprising hexamethylenetetramine and silver ions bound to 1, 2-diaminoethane and heating the impregnated carrier at a temperature at which silver is formed. The heating may be at 50-100‹C and be followed by heating at 125-400‹C to fix the silver on the carrier which may contain SiO 2 and/or Al 2 O 3 The impregnating solution may also contain an alkali metal compound.
