    Abstract: PROBLEM TO BE SOLVED: To provide a process for catalytically hydrogenating a hydrocarbon stream by which the fewest possible undesired secondary components such as oligomers and/or polymers and/or cracking products are formed. SOLUTION: The hydrocarbon stream is catalytically hydrogenated by adding a basic compound to the starting material stream without using a different solvent from the hydrocarbon stream to be hydrogenated. Thereby, the formation of undesired secondary components on the catalyst is effectively prevented. COPYRIGHT: (C)2003,JPO

    Abstract: The invention relates to a method for catalytically hydrating a poly- or monomethylol alkanal of the general formula (I), wherein R is the same or different and may represent a substituted or unsubstituted aliphatic hydrocarbon with 6 to 22 carbon atoms, an aryl or arylalkyl group with 6 to 22 carbon atoms or a methylol group, in the presence of a copper-containing catalyst. The inventive method is characterized in that the poly- or monomethylol alkanal containing batch to be hydrated has a total content of up to 5 ppm of metal ions of the groups 3 to 14 of the periodic system.

    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).
