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 concerns a process for preparing 1,4-butanediol by continuous catalytic hydrogenation of 1,4-butinediol in that 1,4-butinediol is reacted with hydrogen in the liquid continuous phase in th e presence of a heterogeneous hydrogenation catalyst at temperatures of between 20 and 300 .degree.C, a pressure of between 1 and 20 0 bar and values of the liquid-side mass transfer coefficients k L a, relative to the volume, of between 0.1 s-1 and 1s-1, a) with a catalyst suspended in the reaction medium, wherein, when a packed bubble column is used, it is operated in the upwards mode and at a ratio of the amount of gas leaving the reaction vessel to the amount fed thereto of between 0.99:1 and 0.4:1, or b) is guided upwards in parallel flow throug h a fixed bed reactor operated in the circulating gas mode, the ratio between the amount of gas fed to the reaction vessel and the amount of gas leaving the latter being maintained between 0.99:1 and 0.4:1.

Abstract: A process for preparing tetrahydrofuran, which comprises reacting 1,4-butenediol diethers of the formulae I and/or IIwhere the R radicals can be identical or different and are C1-C15-alkyl or cycloalkyl radicals, C6-C12-aryl radicals or C7-C15-aralkyl radicals, with water and hydrogen at from 20 to 300° C. under from 1 to 300 bar in the presence of catalysts or catalyst combinations which comprise components which are both capable of hydrogenation and have acidic or basic centers and a novel process for preparing 1,4-butanediol diethers of the formula I by metathesis are described.

Abstract: A process for the separation by distillation of a mixture of 1,4-butanediol and at least one 4-hydroxybutyraldehyde, its cyclic hemiacetal and its cyclic full acetals with at least one further alcohol by carrying out the distillation in the presence of an alkaline compound. The mixture to be separated preferably contains a cyclic full acetal of 4-hydroxybutyraldehyde with a further alcohol which has a lower boiling point than butanediol and also the further alcohol in free form. The process is particularly suitable for the separation by distillation of mixtures formed in the hydrogenation of maleic acid derivatives.
