    Abstract: In a process for hydrogenating unsubstituted monocyclic or polycyclic aromatics or monocyclic or polycyclic aromatics substituted by at least one alkyl group, amino group or hydroxyl group or a combination of two or more thereof to form the corresponding cycloaliphatics by means of gaseous hydrogen in the presence of at least one catalyst in a reaction column (4) in which the reactants are passed over the catalyst(s) (5) fixed in the reaction column (4), the cycloaliphatics are taken off at a side offtake (14) or from the bottom of the column (6) through a line (8) or at the side offtake (14) and from the bottom of the column (6) through a line (8).

    Abstract: A process for preparing N-alkenyl-amides by reacting the corresponding NH-amides with acetylenes in the liquid phase in the presence of basic alkali metal compounds and of a cocatalyst comprises using as the cocatalyst diols of the general formula (I)where Xis branched or unbranched alkylene selected from the group consisting ofwhere R1 to R6 are independently hydrogen or C1- to C4-alkyl;orbranched or unbranched cyclic alkylene of 3 to 14 carbon atoms including 3 to 12 ring carbon atoms,their monoalkenyl ethers, their dialkenyl ethers or mixtures thereof.

    Abstract: Alkenyl ethers are prepared by reacting the corresponding alcohols or phenols with acetylenes in the liquid phase in the presence of basic alkali metal compounds and a cocatalyst comprising compounds of the formula (Ia) and/or (Ib)R1O-(CH2CH2CH2CH2O)n-H (Ia)R1O-(CH2CH2CH2CH2O)n-H2, (Ia)where R1, R2 are, independently of one another, C1-C6-alkyl or C2-C6-alkenyl, or R1 and R2 together form a butyl unit and n is 1, 2, 3, 4 or 5.

    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: A process for the production of amines comprises catalytic hydrogenation-amination of carbonyl compounds and/or alcohols containing at least 50 ppm halogen (with respect to the mixture ) with nitrogen compounds in the presence of Co and/or Ni containing catalysts and solid acid cocatalysts. A process for the production of amines of formula R R CH-NR R (1) by catalytic hydrogenation-amination of carbonyl compounds of formula R -C(=O)-R (2) and/or alcohols of formula R -CH(OH)-R (3) containing at least 50 ppm halogen (with respect to the mixture ) with nitrogen compounds of formula HNR R (4) in the presence of Co and/or Ni containing catalysts and solid acid cocatalysts. R -R = H, 1-12C alkyl, 3-12C cycloalkyl, 6-10C aryl or 7-11C aralkyl.
