    摘要: The invention relates to a continuous method for producing para-alkyl substituted cyclohexylmethanols, in particular 4-isopropylcyclohexylmethanol, by catalytic hydrogenation of the corresponding aldehyde or ketone in the presence of hydrogen and in the presence of a catalyst, comprising ruthenium applied to a carrier as an active metal, wherein the carrier comprises AI
    2 O
    3 and/or SiO
    2 and wherein the catalyst is used in the form of a fixed bed catalyst in a hydrogenation reactor or in a plurality of hydrogenation reactors connected consecutively.
