Abstract: A supported catalyst (I) containing 0.1-20 wt.% rhenium and 0.05-10 wt.% platinum (with respect to the total weight of the catalyst) is prepared by: (a) treatment of the optionally pretreated support with a solution of a rhenium compound; (b) drying and heating in a reducing atmosphere at 80-600 degreesC and; (c) impregnation with a solution of a platinum compound and drying. An Independent claim is also included for a process for the production of alcohols by catalytic hydrogenation of carbonyl compounds using the catalyst (I).

Abstract: The present invention relates to a process for separating off solvents from solvent-comprising hydrogenation outputs from a catalytic hydrogenation process, which comprise at least one water-soluble hydrogenation product having at least one alcohol, lactone, ether, lactam or amino group in a solvent which is immiscible or not completely miscible with water and has a boiling point below 100° C., wherein water is added to the hydrogenation output, the solvent-comprising phase is separated off and recirculated to the hydrogenation.

Abstract: The present invention provides a process for preventing fumaric acid deposits in the preparation of maleic anhydride, comprising the following steps: a) absorption of a C4-dicarboxylic acid or of a derivative from a crude product mixture into an organic solvent or water as an absorbent, b) removal of the C4-dicarboxylic acid or of a derivative from the absorbent, the absorbent thus recovered being catalytically hydrogenated fully or partly and recycled fully or partly into the absorption stage (a).
