無水マレイン酸の水素化によるテトラヒドロフランの選択的製法

Japanese Patent JP2004538134

A

A catalyst (I) for the gas phase hydrogenation of 4C-dicarboxylic acids and/or derivatives, preferably maleic acid anhydride, comprises copper oxide (20-94 wt.%), palladium and/or a palladium compound (0.005-5 wt.%) and an oxide support (2-79.995 wt.%) comprising oxides of Al, Si, Zn, La, Ce, Group IIIa-VIIIa elements and/or Group IA and II elements. Independent claims are also included for: (i) a process for the production of the catalyst (I) by impregnation of an oxide supported copper oxide catalyst with a solution of a soluble palladium compound, drying and optionally calcining; and (ii) a process for the gas phase hydrogenation of 4C-dicarboxylic acids and/or derivatives, preferably maleic acid anhydride in the presence of the catalyst (I).
