摘要： The invention relates to a method for the hydrogenation of oligo- and/or polyesters which can be obtained by the esterification of a dicarboxylic acid solution with a diol or diol mixture, the hydrogenation being carried out in the presence of a catalyst, the precursor of said catalyst containing copper oxide, aluminum oxide and at least one oxide of lanthanum, iron, tungsten, molybdenum, titanium or zirconium. The invention also relates to a method for producing 1,6-hexanediol by the catalytic hydrogenation of ester mixtures which contain oligo- and polyesters of the adipic acid and 6-hydroxycaproic acid as the main components and which can be obtained by the esterification of a dicarboxylic acid solution with diols and especially 1,6-hexanediol or diol mixtures.

摘要： The invention relates to a method for increasing yield in the production of polyvalent alcohols, especially trimethylolpropane, obtained by condensing formaldehyde with a higher aldehyde. According to the inventive method, acid treatment is carried out on a mixture (high-boiling fraction) that is obtained by reprocessing, contains derivatives of said alcohols and has a higher boiling point than the respective alcohol, and the polyvalent alcohol is recovered from the acid-treated high-boiling fraction. The inventive method is characterised in that the water content of the high-boiling fraction amounts to between 20 and 90 wt. % in relation to the entire mixture of the high-boiling fraction and water.

摘要： The present invention relates to a process for recovering components from a low boiler mixture which is obtained in the distillation of hydrogenation effluents from the preparation of polymethylols, by multistage distillation of the low boiler mixture comprising a tertiary amine, water, methanol, polymethylol of the formula (I) methylolalkanal of the formula (II) alcohol of the formula (III) and an alkanal with a methylene group in the α position to the carbonyl group, and in which each R is independently a further methylol group or an alkyl group having 1 to 22 carbon atoms or an aryl or aralkyl group having 6 to 22 carbon atoms, a first distillation stage involving separating the low boiler mixture into a higher-boiling, predominantly water-rich fraction and into a lower-boiling aqueous organic fraction comprising the tertiary amine, and the second distillation stage involving separating the aqueous organic fraction from the first distillation stage into a predominantly amine-containing fraction and a further amine-depleted fraction, wherein the tertiary amine is trimethylamine or triethylamine, and the bottom temperature in the second distillation stage is 110° C. and more.
