A continuous process for the production an aldehyde by hydroformylation of an optionally substituted alpha-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 alpha-olefin to the hydroformylation zone;
maintaining temperature and pressure conditions in the hydroformylation zone conducive to hydroformylation of the alpha-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.
一种通过对任选取代的α-烯烃进行加氢甲酰化生产醛的连续工艺包括:提供一个加氢甲酰化区,该区含有一定量的液体反应介质,其中溶解有复合铑加氢甲酰化催化剂,该催化剂由铑与一氧化碳和环状亚磷酸酯复合而成,环状亚磷酸酯具有与三个氧原子相连的桥头磷原子,其中至少有两个氧原子与桥头磷原子一起形成环的一部分;向加氢甲酰化区提供所述的α-烯烃;在加氢甲酰化区保持有利于α-烯烃加氢甲酰化的温度和压力条件;向加氢甲酰化区提供补给氢和一氧化碳;从液体加氢甲酰化介质中回收包括至少一种醛的加氢甲酰化产物。
