Abstract
A continuous hydroformylation process for producing an aldehyde comprising 1) reacting an olefinically unsaturated compound, carbon monoxide and hydrogen in the presence of a rhodium-organobisphosphite complex catalyst at a partial pressure of carbon monoxide and hydrogen, and 2) exposing a mixture comprising at least a portion of the catalyst of 1) to a gaseous mixture comprising hydrogen at a pressure that is greater than the partial pressure of carbon monoxide and hydrogen during the reaction.
