    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: Disclosed is a method for jointly producing (i) formic acid (III); (ii) a carboxylic acid comprising at least two carbon atoms (II) and/or the derivatives thereof; and (iii) a carboxylic acid anhydride (VII). According to said method, (a) a formic acid ester (I) is transesterfied to formic acid (III) and the corresponding carboxylic acid ester (IV) by means of a carboxylic acid comprising at least two carbon atoms (II); (b) at least one portion of the carboxylic acid ester (IV) formed in step (a) is carbonylated in order to obtain the carboxylic acid anhydride (V); and (c) at least one portion of the carboxylic acid anhydride (V) formed in step (b) is further dehydrated by means of a carboxylic acid (VI) so as to form a carboxylic acid anhydride (VII) and the carboxylic acid (II).

    Abstract: A process for separating a mixture comprising a) a monoolefinically unsaturated compound which is obtainable by adding two terminal olefins which bear the functional groups required to prepare the monoolefinically unsaturated compound containing at least two functional groups, or a saturated compound obtained by hydrogenating such a compound, b) a compound which is obtainable by adding more than two of the terminal olefins mentioned in a) or a compound obtained by hydrogenating such a compound, and c) a compound which contains a transition metal, is homogeneous with respect to the mixture and is suitable as a catalyst for preparing a monoolefinically unsaturated compound by adding two terminal olefins which bear the functional groups required to prepare the monoolefinically unsaturated compound containing at least two functional groups, by means of a semipermeable membrane to obtain a permeate and a retentate in such a way that the weight ratio of component b) to component c) in the mixture fed to the semipermeable membrane is smaller than in the retentate.
