摘要： An improvement in the process for the manufacture of predominantly straight-chain aldehydes by hydroformylation of olefinically unsaturated compounds of 2 to 20 carbon atoms with carbon monoxide and hydrogen in which, in a first stage, aqueous cobalt solutions are treated with carbon monoxide and hydrogen at temperatures of 50.degree. to 200.degree.C and pressures of 100 to 400 atmospheres in the presence of active charcoal, zeolites or basic ion exchangers which are charged with cobalt carbonyl, in a second stage cobalt carbonyl-hydride is extracted from the reaction mixtures thus obtained, at temperatures of 20.degree. to 180.degree.C and pressures of 1 to 400 atmospheres, by means of olefinically unsaturated compounds which must be water-insoluble and liquid under the conditions used, the aqueous phase is separated off and the organic phase is transferred to a third stage and in this stage, after introducing olefinically unsaturated compounds if the latter have only been used partially for the extraction, the hydroformylation is carried out at temperatures of 70.degree. to 170.degree.C and pressures of 100 to 400 atmospheres, the improvement being that the extraction in the second stage is carried out as a co-current extraction whilst maintaining turbulent flow.

摘要： An improved process for the production of aliphatic or cycloaliphatic dialdehydes or acetals of the same by reaction of an aliphatic or cycloaliphatic conjugated diene with carbon monoxide and hydrogen in the presence of a rhodium catalyst which is modified with a tertiary phosphine or phosphite at a temperature of from 70.degree. to 160.degree. C and at a pressure of from 100 to 600 atmospheres, the improvement consisting in using as catalyst a rhodium complex which contains carbon monoxide, a tertiary organic phosphine or tertiary organic phosphite and a halogen atom as ligands. Aliphatic and cycloaliphatic dialdehydes or the acetals of the same are suitable for the production of the corresponding diols which may be used in the production of polymers and particularly of polyurethanes.
