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 preparation of 1,6-hexanediol and 6-hydroxycaproic acid or esters thereof by catalytic hydrogenation of adipic acid, adipic acid monoesters or adipic acid diesters or streams of starting material which contain adipic acid or esters thereof as essential constituents, in which the bottom product obtained in the distillation of the hydrogenation product, following removal of the hexanediol and hydroxycaproic acid or esters thereof, and essentially comprises oligomeric esters of 6-hydroxycaproic acid, is recycled to the hydrogenation, and the resulting mixture of starting material and recycle stream is reacted at from 100 to 300°C., at from 10 to 300 bar in the liquid phase and at a molar ratio of carboxyl groups to be hydrogenated to hydrogen in the reactor of from 1:5 to 1:100 on hydrogenation catalysts is described.

Abstract: Purification of alkenyl compounds with a 2- or 3- times bonded heteroatom alpha to the double bond involves \- 2 distillations to condense purified alkenyl compounds from the gas phase, the process being such that: (i) the time gap between the first distillation following the synthesis and any further distillation is \- 1 day; and (ii) the purified compound has an APHA color index below 30.
