    Abstract: PROBLEM TO BE SOLVED: To provide a method of producing glyoxal diacetal that uses a water- miscible alcohol and permits the continuous operation in high yield. SOLUTION: The reaction of 40-75 wt.% of glyoxal aqueous solution with a monohydric alcohol is carried out in the presence of an acid catalyst to produce a glyoxal diacetal. In this case, a liquid mixture including the alcohol and glyoxal in at least 15:1 molar ratio and water in an amount of ≤8 wt.% at the start of the reaction is brought into contact with an acid catalyst so that the alcohol used may not be distilled off over 5 wt.% until the concentration of the diacetal formed in the reaction mixture attains at least 70% of the equilibrium concentration.

    Abstract: The invention relates to a method for producing optionally akyl-substituted 1,4-butandiol by two-stage catalytic hydration in the gaseous phase of C4 dicarboxylic acids and/or the derivatives thereof with the steps of: a) introducing a gaseous flow of a C4 dicarboxylic acid or a derivative thereof at 200 to 300 °C and 2 to 60 bar in a first reactor and catalytic gas phase hydration to a mainly optionally alkyl-substituted gamma-butyrolactone containing product; b) introducing the product flow so obtained into a second reactor at a temperature of from 150 °C to 240 °C and a pressure of from 15 to 100 bar and catalytic gas phase hydration to optionally alkyl-substituted 1,4-butandiol; c) removing the desired product from the intermediates, byproducts and possibly not reacted educt; d) optionally returning non-reacted intermediates to one or both hydration stages, whereby in both hydration stages one catalyst each is used which comprises = 5 % by weight, preferably 5 to 95 % by weight, especially 20 to 90 % by weight of an oxidic carrier, the pressure prevailing in the second reactor is higher than in the first reactor, and the product mixture removed from the first reactor is introduced into the second reactor without further purifying it.

    Abstract: 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).
