ABSTRACT:
1,3-Butadiene is hydroformylated at 60.degree. 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-five carbon aldehydes and their secondary products. The latter, in particular, can be hydrogenated to 2-propylheptanol, useful as the alcohol component of phthalic ester plasticizers.
