Abstract: Hexanediol is prepared by hydrogenating dialkyl adipates or mixtures which contain a dialkyl adipate as the essential component and organic halogen compounds as impurities, by a process in which, before the hydrogenation, the dialkyl adipates or the mixtures containing dialkyl adipates are passed at from 50 to 250° C. and from 1 to 100 bar over copper catalysts which have a copper content, calculated as CuO, of from 0.5 to 80% by weight, a surface area of from 5 to 1500 m2/g, a porosity of from 0.05 to 1.5 cm3/g and a copper surface area of from 0.1 to 20 m2/g, in order to remove the organic halogen compounds.

Abstract: The hydrogenation of esters of benzene-dicarboxylic acids is carried out on supported catalysts containing a Sub-Group VIIII metal on a macroporous support. A process for the hydrogenation of benzene-dicarboxylic acid ester(s) with hydrogen in presence of a supported catalyst containing Sub-Group VIII metal(s) on a macroporous support. If the ester is dimethyl terephthalate, this excludes hydrogenation on a catalyst containing ruthenium, with or without Sub-Group I, VII or VIII metal(s), on a support with an average pore diameter (APD) of at least 50 nm and a BET surface of not more than 30 m /g, with an active metal content of 0.01-30 wt.% and a ratio of (active metal surface):(support surface) of less than 0.05, and/or on a catalyst containing 0.01-30 wt.% active metal(s) as above on a support in which 10-50 vol.% of the pores consist of macropores with a diameter of 50-10,000 nm and 50-90 vol.% consist of mesopores with a diameter of 2-50 nm.

Abstract: The invention relates to a process for the separation of maleic anhydride from the maleic anhydride-containing reactor offgases from the preparation of maleic anhydride by the oxidation of hydrocarbons, in which this gas stream is brought into contact with a high-boiling, inert absorbent for maleic anhydride and maleic anhydride is separated from the resultant liquid absorbate phase by vapor stripping, where the stripping agent used is an alcohol, and at least some of the maleic anhydride is reacted with the alcohol to give the ester.
