摘要： The present invention relates to a process for producing alcohols by hydrogenation of C9 aldehydes. The process according to the invention is performed in two consecutive hydrogenation stages, wherein the first hydrogenation stage employs an activated metal catalyst based on a nickel metal foam and the second stage employs a supported catalyst containing a catalytically active component from the group consisting of nickel, copper, chromium and mixtures thereof.

摘要： A process for ring hydrogenation of dialkyl terephthalates having C3- to C16-alkyl groups can be performed in a hydrogenation unit composed of two reaction units in series. In the process, a suitable process parameter in relation to the first reaction unit is adjusted so that a certain reaction conversion is achieved.
