Abstract
In the process for hydroformylation of 1,3-butadiene with carbon monoxide and hydrogen to form pentenals, the improvement comprising effecting the hydroformylation with 1,3-butadiene dissolved in an inert reaction medium at 100.degree. to 180.degree. C. at 5 to 35 MPa in the presence of an aqueous solution of a rhodium/phosphine complex and optionally a further phosphine as catalyst.
