Abstract
A method for the production of aliphatic alcohols and/or their ethers, comprising the step of reacting a substrate of the general formula (I): in which m is 0, 1, 2, 3, 4, 5, 6, 7, 8 or 9 and n is 1 or 2; R1 is hydrogen, a linear, branched or cyclic alkyl rest, a primary alkanol rest, an aryl rest or one of the following radicals: and R2 is hydrogen or —CHOH; with hydrogen in the presence of a hydrogenation catalyst system, wherein the hydrogenation catalyst system comprises: a hydrogenation catalyst comprising Re, Fe, Ru, Os, Co, Rh, Ir, Ni, Pd and/or Pt; and an acidic additive selected from the group of organoperfluorocarboxylic acids, hydrochloric acid, formic acid, acetic acid, phosphoric acid, sulfuric acid, sulfonic acid and/or organic compounds comprising sulfonic acid groups, phosphoric acid groups and/or phosphonic acid groups; with the proviso that the acidic additive is a liquid and/or at least partially dissolved in the substrate (I) during the reaction of (I) with hydrogen in the case that R2 is CHOH.
