A process for the production of a non-linear aldehyde by hydroformylation of an optionally substituted internal olefin comprises:
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 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;
supplying said internal olefin to the hydroformylation zone;
maintaining temperature and pressure conditions in the hydroformylation zone conducive to hydroformylation of the internal 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 non-linear aldehyde.
