Title
(EN) Process for the preparation of aldehydes by hydroformylation of olefins
Abstract
(EN)

A process for the production of an aldehyde by hydroformylation of an olefin comprises: PA1 providing a hydroformylation zone containing a charge of a liquid reaction medium having dissolved therein a complex rhodium hydroformylation catalyst comprising rhodium in complex combination with carbon monoxide and with an organic phosphite ligand of the general formula: EQU (RO).sub.3 P (I) PA1 in which each R represents an optionally substituted hydrocarbyl radical; PA1 supplying said olefin to the hydroformylation zone; PA1 maintaining temperature and pressure conditions in the hydroformylation zone conducive to hydroformylation of the olefin; PA1 supplying make-up hydrogen and carbon monoxide to the hydroformylation zone; PA1 recovering from the liquid hydroformylation medium a hydroformylation product comprising at least one aldehyde; and PA1 supplying make-up phosphite ligand to the hydroformylation zone at a rate sufficient to maintain a predetermined level of free phosphite ligand in the hydroformylation medium.
