Described is a process for producing 1-(4-isobutylphenyl)ethanol by reacting 1-(4-isobutyl-phenyl)ethanone with hydrogen in the presence of a catalyst composition comprising cop-per and one or more metals other than copper, and a use of a respective composition and/or of a pre-composition, the pre-composition comprising a mixture of oxides of copper and oxides of one or more metals other than copper, in a catalytic hydrogenation process for producing 1-(4-isobutylphenyl)ethanol from 1-(4-isobutylphenyl)ethanone.

Process for producing 1-(4-isobutylphenyl)ethanol by hydrogenation of 1-(4-isobutyl-phenyl)ethanone in the presence of a catalyst composition comprising copper

The invention relates to a method of performing a chemical reaction under elevated pressure. It is suggested that the method comprises the steps of pressurizing a first vessel () and a second vessel () with reactant-containing liquid and gas to a predetermined pressure, providing reaction conditions in one of the vessels () such that the chemical reaction is effected and a product-containing liquid is obtained, withdrawing liquid from the respective vessel () as reaction product when a predetermined amount of reaction product has formed, preferably after the chemical reaction in the respective vessel () has concluded, and synchronously supplying reactant-containing liquid to the respective other vessel (), wherein the first and second vessels () are in fluid communication by way of a gas communication passage (). The invention also relates to an apparatus and use thereof for performing said chemical reaction.
