    摘要: The present invention provides a process, which includes: in a homogeneous liquid phase including water, and over a fixed-bed catalyst, continuously hydrogenating at least one hydroformylation product obtained from a hydroformylation of one or more C4-16 olefins to produce at least one output mixture; wherein the fixed-bed catalyst includes at least one element of transition group eight of the Periodic Table of the Elements; wherein the output mixture includes at least one corresponding alcohol and from 0.05 to 10% by weight of water; and wherein in a steady-state operation of the process, from 3 to 50% more hydrogen is fed to the hydrogenation than is consumed by the hydrogenation.

    摘要: A process for preparing benzoic esters whose alkoxy groups have from 7 to 13 carbon atoms by reacting benzoic acid with at least one alcohol having from 7 to 13 carbon atoms, the water of reaction formed being removed during the esterification reaction by distillation, and the alcohol not converted in the esterification reaction being removed after the esterification reaction, in which the reaction takes place in the presence of a tin(II) compound as catalyst and, without treatment with a base, the catalyst and/or its derivatives is/are separated off by filtering or by centrifuging from the reaction mixture which remains after the unconverted alcohol has been separated off.
