Abstract: The invention relates to the preparation of aldehydes by hydroformylation of olefinically unsaturated compounds. The reaction is carried out in the presence of a catalyst system which contains rhodium and an ammonium salt, which is soluble in organic media, of a sulfonated phosphorous acid triester.

Abstract: of the disclosure 1,3-Butadiene is hydroformylated at 60 to 150.degree.C and 1 to 20 MPa in the presence of an aqueous solution which contains, as catalyst, at least one water-soluble rhodium compound and at least one water-soluble organic phosphine. A pH of 8 to 11 is maintained in the aqueous catalyst solution to increase the selectivity of the reaction with respect to the formation of n-C5 aldehydes and secondary products of the n-C5 aldehydes.

Abstract: The characteristic features in the hydroformylation of olefinically unsatd. cpds. to give prods. non- (or only slightly)-soluble in water are that (i) the olefinic cpd. is in homogeneous phase in a polar organic solvent in presence of a catalyst system comprising (a) an Rh carbonyl cpd. and (b) a solvent- and also water-soluble salt of a sulphonated or carboxylated organic mono- or poly-phosphine; (ii) reaction is at 60-180 degrees C/2-35 MPa with CO and H2; and (iii) prod. recovery is by distilling off the organic solvent and separating off the catalyst system from the distn. residue using water.

Abstract: The characteristic features in the prepn. of pentenals are that: (i) 1,3-butadiene is dissolved in an inert medium; and then (ii) hydroformylation is effected at 100-180 degrees C/5-35 MPa in presence of an aq. soln. contg. an Rh/phosphine complex (opt. together with further phosphine) as catalyst.
