Abstract: The invention concerns a method for producing optically active hydroxy-, alkoxy-, amino-, alkyl-, aryl- or chlorine-substituted alcohols or hydroxycarboxylic acids having 3 to 25 carbon atoms or their acid derivative s or cyclization products by hydrogenating the correspondingly substituted optically active monocarboxylic acids or dicarboxylic acids or their acid derivatives in the presence of a catalyst whose active constituent consists of rhenium or contains rhenium and at least one additional element of atomic numbers 22 to 83, with the provisions that: a) the at least one additional element of atomic numbers 22 to 83 is not rhenium, and; b) when producing optically active 2-amino-, 2-chloro-, 2-hydroxy- and 2-alkoxy-1-alkanols by the catalytic hydrogenation of correspondingly optically active 2-amino-, 2- chloro-, 2-hydroxy- and 2-alkoxy carboxylic acids or their acid derivatives, the at least one additional element of atomic numbers 22 to 83 is not palladium nor platinum.

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).

Abstract: Production of 1,6-hexanediol of purity at least 99.5 % comprises: (1) catalytically dimerizing a 1-8C acrylic acid ester in presence of rhodium compounds to a mixture mainly of 2- and 3-hexenedioic acid diesters; (2) hydrogenating the ester mixture in chromium-free mainly copper-containing catalysts; and (3) purifying the resulting diol mixture by fractional distillation.

Abstract: Disclosed is a biodiesel fuel mixture having a cetane number of> 40, comprising a) from 5 to 90% by weight of biodiesel, b) from 0 to 94% by weight of diesel oil of fossil origin, c) from 1 to 20% by weight of a polyoxyalkylene dialkyl ether of the formula RO(CH2O)nR, in which R is an alkyl group having from 1 to 10 carbon atoms and n is from 2 to 10, and d) from 0 to 5% by weight of further additives. Also disclosed is the use of polyoxymethylene dialkyl ethers as defined above as an additive in biodiesel fuel mixtures with at least 1% by weight of biodiesel for increasing the cetane number.
