ABSTRACT:
In a process for producing an aldehyde by hydroformylation comprising reacting an olefin with carbon monoxide and hydrogen in the presence of a solution of a rhodium-tertiary phosphine complex catalyst and recycling the catalyst-containing solution to the reaction zone after recovering the aldehyde formed by distillation in a distillation zone, the catalyst inactivated by the hydroformylation is reactivated effectively by treating the catalyst-containing solution with carbon dioxide.
