Abstract

In the hydroformylation of olefins having 6 to 20 carbon atoms in the presence of a cobalt catalyst in the presence of an aqueous phase with thorough mixing in a reactor, a hydroformylation products-containing first stream is withdrawn at the top of the reactor and an aqueous phase-containing second stream is withdrawn from the bottom of the reactor. The flow rate of the second stream is controlled in accordance with a temperature which is measured at a point in the bottom of the reactor or in a line leading out of the bottom of the reactor. The yield of crude hydroformylation product is increased as a result of stable sustained operation.
