    摘要: Preparation of C.sub.3 - to C.sub.25 -alkanols by catalytic hydrogenation of corresponding crude C.sub.3 - to C.sub.25 -alkanols, as obtained in the cobalt-catalyzed hydroformylation of C.sub.2 - to C.sub.24 -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 C.sub.9 -C.sub.11 - and C.sub.13 -C.sub.15 -alkanols which are used to prepare high-grade plasticizer esters.

    摘要: 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.

    摘要: Olefinically unsaturated compounds are hydroformylated continuously, the olefin being passed into the lower region of the reactor, under from 1 to 40 bar and at from 50.degree. to 140.degree. C. with the aid of a rhodium complex as a catalyst in a hydroformylation reactor having a liquid reaction zone which occupies about 60-85% of the reactor volume, the gaseous products and reactants being removed from the hydroformylation reactor, the products being isolated and the major part of the remaining gas being recycled to the reactor by the cycle gas method, by a process in which from 20 to 80% by volume of the cycle gas is fed into the hydroformylation reactor above the liquid reaction zone and/or below the liquid surface in the top fourth of the liquid reaction zone.

    摘要: A process for isolating carboxylic acids from residues of the oxo reaction which are obtained as residues, on hydroformylation of ethylene or propylene, optionally after removing a part of the aldehydes produced, subsequent hydrogenation, treatment with aqueous alkali metal hydroxide solutions and subsequent distillation, wherein the residues are acidified with strong mineral acids to a pH of from 2-4, the acidified mixture not containing more than 5 parts by weight of water per part by weight of the carboxylic acids contained in the mixture, the organic phase is then separated off and the carboxylic acids are isolated therefrom by distillation at pressures below 150 mbar. The carboxylic acids obtained can be used as solvents or for the manufacture of esters.

    摘要: Solutions of cobalt carbonyl and cobalt carbonyl hydride in organic solvents are prepared by treating aqueous solutions of cobalt salts with carbon monoxide and hydrogen at a temperature of from 50.degree. to 200.degree.C and a pressure of from 50 to 500 atmospheres in the presence of solvents which are sparingly water-miscible or are water-immiscible and which have a content of cobalt carbonyl, cobalt carbonyl hydride or mixtures thereof, the starting materials and the organic solvents being passed cocurrently through a zone in which a turbulent flow is maintained. The improvement includes using n-butanol as solvent. Solutions of cobalt carbonyl and cobalt carbonyl hydride in n-butanol are suitable as catalyst solutions for oxo syntheses.
