    摘要： The invention relates to a method for preparing at least one unsaturated alcohol (B). The method comprises the following steps (I) to (III): (I) reaction of at least one alkali or alkaline earth hydroxide with at least one alcohol (A) in at least one organic solvent (L) so that a mixture (G-I) is obtained which contains at least the alcohol (A), the solvent (L) and an alcoholate (AL); (II) reaction of at least one carbonyl compound of the general structure R-CO-R' with at least one alkine of the general structure R"-CC-H and the mixture (G-I) obtained in step (I) above, so that a mixture (G-II) is obtained which contains at least the alcohol (A), the solvent (L) and an unsaturated alcohol (B); and (III) distillation of the mixture (G-II) obtained in step (II) above so that the at least one alcohol (B) and a mixture (G-III) containing the solvent (L) and the alcohol (A), are obtained. Said method is characterized in that the solvent (L) and the alcohol (A) obtained in step (III) are fed back to step (I) as a mixture.

    摘要： A method for producing butyrolactones of general formula (I), wherein the substituents R?1 and R2¿ stand for hydrogen, alkyl, aryl hydroxyalkyl or optionally substituted aryl and trialkylsilyl groups, by reacting alkynes of general formula (II) R1-C C-R2, wherein R?1 and R2¿ have the above-mentioned meaning, with carbon monoxide and water in the presence of a rhodium catalyst at pressures ranging from 20 to 300 bars and by hydrogenation of intermediately formed and as yet non-hydrogenated 2(5H) furanones. According to the inventive method a) the reaction carbonylation mixture is reacted with hydrogen at temperatures of 150-250 °C and at pressures ranging between 100 and 300 bars, b) the precipitated catalyst is separated and returned to the cabonylation reaction and c) butyrolactone is obtained from the de-catalysed reaction mixture by means of distillation.

    摘要： The invention relates to selected cyclohexane-1,3- and 1,4-dicarboxylic acid esters, to their use as plasticizers in synthetic materials and to their production. The inventive method of production comprises hydrating the corresponding isophthalic acid and terephthalic acid esters by contacting one or more of such isophthalic acid or terephthalic acid esters with a hydrogen-containing gas in the presence of a catalyst. Said catalyst contains as the active metal at least one metal of subgroup VIII of the periodic system alone or together with at least one metal of subgroup I or VII of the periodic system, applied on a substrate. The inventive method is further characterized in that the substrate is macroporous.

    摘要： The invention relates to a method for hydrogenating a benzene polycarboxylic acid or a derivative thereof or of a mixture comprised of two or more thereof with a gas containing hydrogen in the presence of a catalyst. Said catalyst comprises ruthenium as an active metal which is deposited alone or together with at least one metal of subgroups I, VII, or VIII of the periodic table on a support, whereby the support contains macropores. The invention also relates to novel hydrogenated products obtained by hydrogenating benzene polycarboxylic acid (derivatives) and to the use thereof as plasticizers in plastics.
