    Abstract: The invention relates to a method for producing 1,6-hexanediol having a purity of > 99.5 wt. % by catalytic dimerisation of acrylic acid esters, catalytic hydrogenation of the thus obtained hexene diacidic diester in order to form 1.6-hexanediol. Said method consists in: a) dimerising C1- C8-acrylic acid esters in the presence of at least one rhodium compound in order to form mixtures predominantly of 2- and 3-hexene diacdic diesters, b) hydrating the obtained dimerisation discharge in the presence of chrome-free catalysts containing mainly copper as a hydrogenation component and c) purifying the thus obtained raw 1.6-hexanediol by fractionating distillation.

    Abstract: A process for the hydrogenation of an organic compound containing at least one carbonyl group comprises bringing the organic compound in the presence of hydrogen into contact with a shaped body which can be produced by a process in which (i) an oxidic material comprising copper oxide, aluminum oxide and aluminum oxide is made available (ii) pulverulent metallic copper, copper flakes, pulverulent cement, graphite or a mixture thereof is added to the oxidic material, and (iii) the mixture resulting from (ii) is shaped to form a shaped body.

    Abstract: The present invention provides a process for preparing 1,6-hexanediol by hydrogenating dialkyl adipates, alkyl 6-hydroxycaproates, 1,4-cyclohexanedione and 4-hydroxycyclohexan-1-one as ester mixtures comprising impurities, by a) freeing resulting the esterification mixture of excess alcohol and low boilers in a first distillation stage (alcohol removal), b) carrying out a separation of the bottom product in a second distillation stage into an ester fraction substantially free of 1,4-cyclohexanediols and a fraction comprising at least the majority of the 1,4-cyclohexanediols, c) catalytically hydrogenating the ester fraction substantially free of 1,4-cyclohexanediols (ester hydrogenation) and d) in a purifying distillation stage, obtaining 1,6-hexanediol from the hydrogenation effluent in a manner known per se, which comprises selectively hydrogenating the ester mixture before stage a) and/or before stage b) (purifying hydrogenation).
