Process for the hydroformylation of olefinically unsaturated compounds

摘要

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.
