Abstract: Aldehydes are obtained from the gaseous product of the hydroformylation of olefinically unsaturated compounds using a rhodium catalyst by a process (cf. FIG. 2) in which (a) this gaseous product is introduced, without being cooled or depressured, into a distillation column D, (b) the top fraction from this column is cooled in a condenser K so that the greater part of the aldehydes contained therein is condensed, (c) the condensate is separated, in a separator A, into a gas phase and a liquid phase, (d) the gas phase from A, after waste gas has been separated off, is again brought to the hydroformylation pressure by means of a compressor P, and is returned to the reactor as a recycle gas, (e) the liquid phase from A is returned to D, and (f) the aldehydes are taken off from column D as liquid bottom products and/or as a vaporous side stream.

Abstract: Preparation of C3- to C25-alkanols by catalytic hydrogenation of corresponding crude C3- to C25-alkanols, as obtained in the cobalt-catalyzed hydroformylation of C2- to C24-olefins, by partial 80-95% hydrogenation conversion in a first stage using a silica supported nickel and molybdenum oxide catalyst and then completing the conversion in a second stage using a cobalt catalyst containing copper, manganese, molybdenum and,optionally other activating additives. The process is especially adapted to the economic preparation of C9-C11- and C13-C15-alkanols which are used to prepare high-grade plasticizer esters.

Abstract: Preparation of C3-C5-alcohols by hydrogenation of the corresponding aldehydes with hydrogen by means of a catalyst which, in ready-to-use but not yet reduced form, contains 5 to 70 % by weight of Al2O3 and/or Fe2O3 and 30 to 95 % by weight of a mixture of 100 parts by weight of NiO, 20 to 40 parts by weight of CuO, 0.5 to 6 parts by weight of MoO3 and 0 to 10 % by weight of Mn3O4, the catalyst having been prepared by reaction of an aqueous solution of the corresponding metal salts with an alkali metal carbonate solution under specified conditions, followed by drying, washing and heating.
