Proposed is a cylindrical reactor () having a vertical longitudinal axis for continuous hydroformylation of a C-C-olefin or a mixture of C-C-olefins with synthesis gas in the presence of a homogeneously dissolved metal carbonyl complex catalyst,

Cylindrical reactor and use thereof for continuous hydroformylation

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presence of an aqueous phase with thorough mixing in a reactor, a hydroformylation products-containing first stream is withdrawn at the top of the reactor and an aqueous phase-containing second stream is withdrawn from the bottom of the reactor.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

Process for hydroformylation of olefins

The extraction process for removing metal salts from an organic hydroformylation reaction fluid ('HRF') prior to returning the HRF to a reaction zone of a hydroformylation process, the extraction process comprising the step of contacting the HRF with an aqueous buffer solution, is improved by contacting the HRF with water in addition to that present in the aqueous buffer solution, i.e., with added water.
