The catalyst solution used in a hydroformylation process is prepared for storage by first reducing its acid concentration and/or water content, and then storing the solution under a blanket of syngas and/or an inert gas. Alternatively, or in addition to, the catalyst solution can be stored with an aqueous buffer comprising materials that will neutralize and/or absorb the acid species within the catalyst solution.

Method of removing cobalt deposits in a reactor for the cobalt-catalyzed high-pressure hydroformylation of olefins by treatment with aqueous nitric acid, wherein the reactor is at least partly filled with aqueous nitric acid and the temperature of the aqueous nitric acid is increased during the treatment.

Method for removing cobalt deposits in a high-pressure olefin hydroformylation reactor

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presence of an aqueous phase with thorough mixing in a reactor, a hydroformylation products-containing first stream is withdrawn at the top of the reactor and an aqueous phase-containing second stream is withdrawn from the bottom of the reactor.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