  • Patent number: 9115069
    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presence of an aqueous phase with thorough mixing in a reactor, a hydroformylation products-containing first stream is withdrawn at the top of the reactor and an aqueous phase-containing second stream is withdrawn from the bottom of the reactor.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.

  • Patent number: 8404903
    Abstract: A process of controlling heavies in a recycle catalyst stream, particularly, for use in a continuous hydroformylation process of converting an olefin with synthesis gas in the presence of a hydroformylation catalyst to form an aldehyde product stream with subsequent separation of the catalyst for recycle to the hydroformylation step.
