Abstract: A process for catalytically hydrogenating methylolalkanals of the general formula in which R1 and R2 are each independently a further methylol group or an alkyl group having from 1 to 22 carbon atoms or an aryl or aralkyl group having from 6 to 33 carbon atoms, in the liquid phase over a hydrogenation catalyst, which comprises setting a pH of from 7.0 to 9.0 in the hydrogenation effluent by adding at least one tertiary amine, an inorganic base or an inorganic or organic acid to the hydrogenation feed.

Abstract: A process for greatly improving the color index of polyhydric alcohols, especially trimethylolpropane, by hydrogenation comprises using, in the hydrogenation, an alcohol which has already been purified by distillation. The catalysts used are those conventionally employed in hydrogenations, preferably copper, nickel, palladium or ruthenium catalysts.

Abstract: A process for the purification of crude terephthalic acid comprises catalytic hydrogenation using a catalyst material (I) comprising a ca bon supported hydrogenation metal whereby the carbon support comprises carbon fibers. Independent claims are included for: (1) the catalyst material (I) whereby the carbon support has a BET surface area of less than 500 Micro 2>/g; (2) a reactor (II) containing a flat catalyst material in the form of cloth, textile and/or felt comprising a hydrogenation metal applied to carbon fibers and having at least two edges opposite to each other to which the catalyst material is stably affixed or containing the catalyst material in the form of parallel fibers or bands; and (3) a process for the selective hydrogenation of carbon-carbon double or triple bonds and/or hydrogenatable functional groups using the catalyst material (I) or reactor (II).

Abstract: The invention relates to a method for catalytically hydrating a poly- or monomethylol alkanal of the general formula (I), wherein R is the same or different and may represent a substituted or unsubstituted aliphatic hydrocarbon with 6 to 22 carbon atoms, an aryl or arylalkyl group with 6 to 22 carbon atoms or a methylol group, in the presence of a copper-containing catalyst. The inventive method is characterized in that the poly- or monomethylol alkanal containing batch to be hydrated has a total content of up to 5 ppm of metal ions of the groups 3 to 14 of the periodic system.

Abstract: The invention relates to a method for eliminating at least one of the com ponents selected from among the group comprising oxygen, nitrogen oxides, ac etylenes, and dienes, from a gas mixture containing said at least one compon ent in addition to hydrogen, one or several olefins that are no dienes, and other optional gas components. According to said method, the gas mixture is contacted with a catalyst in a reaction zone. The disclosed method is charac terized in that the catalyst contains copper(I) sulfide.
