摘　　要：合成了水溶性膦铑配合物ＨＲｈ（ＣＯ）（ＤＰＭ）３，并研究了其对苯乙烯水相氢甲酰化反应的催化性能，主要考察了催化剂用量、反应温度、压力、Ｖ水／Ｖ烯比、水相ｐＨ值等因素对催化活性和选择性的影响。在９０℃、５．０ＭＰａ（ＣＯ／Ｈ２＝１）、水相ｐＨ＝５．０、Ｖ水／Ｖ烯比为２的条件下反应３ｈ，苯乙烯的转化率达９７．８％，醛收率９４．１％，醛的异／正比为１．５。PM [Ph2P(m-C6H4SO3K )]and its water-soluble rhodium complex, HRh (CO) (DPM)3have been prepared. The catalytic activity and selectivity of HRh(CO) (DPM)3 in styrene hydroformylation are studied in biphasic catalytic system. The amount of HRh(CO) (DPM)3, reaction temperature, pressure, Vwater/Volefin ratio and PH of aqueous phase have great influence on the reaction. Under the conditions of 90℃, 5. 0MPa, Vwater/Volefin ratio, 2, and reaction time, 3h, the conversion of styrene is 97. 8%, aldehyde yield is 94. 1 %, and molar ratio of iso/normal aldehyde is 1. 5.
