Abstract

A continuous hydroformylation process for the production of an aldehyde by hydroformylation of an olefin comprises: PA0 providing a hydroformylation zone containing a charge of a liquid reaction medium having dissolved therein (a) a complex rhodium hydroformylation catalyst comprising rhodium in complex combination with carbon monoxide and with a cyclic phosphite having a phosphorus atom linked to three oxygen atoms at least two of which form together with the phosphorus atom part of a ring and (b) a ligand stabilizing amount of a tertiary amine; PA0 supplying said olefin to the hydroformylation zone; PA0 maintaining temperature and pressure conditions in the hydroformylation zone conducive to hydroformylation of the olefin; PA0 supplying make-up hydrogen and carbon monoxide to the hydroformylation zone; and PA0 recovering from the liquid hydroformylation medium a hydroformylation product comprising at least one aldehyde.
