    • A hydrocarbonylation process for producing an aldehyde or a mixture of a ketone and an aldehyde which comprises:(I) forming a reaction mixture comprising:(a) a catalytic amount of a complex catalyst consisting essentially of rhodium in complex combination with:(i) a triorganophosphine, and(ii) a carboxylic acid having a phenyl group substituted at the para position with a non-reactive electron-withdrawing group, said phenyl group being free of further substitution and said electron withdrawing group being substantially non-reactive in said process;(b) an alpha-olefin having 2 to 5 carbon atoms,(c) carbon monixide, and(d) hydrogenwith the proviso that the reaction mixture has mole ratio of said carbxoylic acid to rhodium of at least about 2; and(II) maintaining the reaction mixture at a temperature and pressure at which said (b), (c) and (d) react to form an aldehyde or a mixture of an aldehyde and a ketone.
    • 用于产生醛或酮和醛的混合物的烃基化方法,其包括:(I)形成反应混合物,其包含:(a)催化量的基本上由铑组成的复合催化剂,其复合组合与:(i) 三有机膦,和(ii)具有在对位被非反应性吸电子基团取代的苯基的羧酸,所述苯基不再进一步取代,并且所述吸电子基团在所述方法中基本上不反应 ; (b)具有2至5个碳原子的α-烯烃,(c)一碳化碳和(d)氢,条件是反应混合物具有至少约2的所述羧甲基酸与铑的摩尔比; 和(II)将反应混合物保持在所述(b),(c)和(d)反应的温度和压力下,形成醛或醛和酮的混合物。
