HYDROFORMYLATION PROCESS

摘要

A process for the production of an aldehyde by hydroformylation of an olefin comprises:… 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 bridgehead phosphorus atom linked to three oxygen atoms at least two of which form together with the bridgehead phosphorus atom part of a ring and (b) a ligand stabilising amount of a tertiary amine;… supplying said olefin to the hydroformylation zone;… maintaining temperature and pressure conditions in the hydroformylation zone conducive to hydroformylation of the olefin;… supplying make-up hydrogen and carbon monoxide to the hydroformylation zone; and… recovering from the liquid hydroformylation medium a hydroformylation product comprising at least one aldehyde.
