Process for the hydroformylation of 1,3-butadiene

摘要

1,3-Butadiene is hydroformylated at 60 to 150 DEG C and 1 to 20 MPa in the presence of an aqueous solution which comprises at least one water-soluble rhodium compound and at least one water-soluble organic phosphine, this solution acting as the catalyst. To increase the selectivity of the reaction with regard to the formation of n-C5-aldehydes and subsequent products of the n-C5-aldehydes, a pH of 8 to 11 is maintained in the aqueous catalyst solution.
