【Abstract】 The catalystic properties of water-soluble rhodium complex,RhCl（Co）（TPPTS）₂ [TPPTS:P（m-C₆H₄SO₃Na）₃],for hydroformylation of the long-chain olefin in the biphasic system and in the presence of CTAB (C₁₆H₃₃Nme₃Br)were studied.The influence of reaction parameters, such as temperature,total pressure,partial pressure ratio of CO to H₂ and molar ratio of TPPTS to Rh,was extensively investigated. The addition of CTAB into the biphasic catalytic system accelerated markedly the reaction rate.Under the reaction conditions: total pressure 1.0 MPa,CO:H₂=1:1,100℃,TPPTS/Rh=16,the turnover frequencies for hydroformylation of 1-hexene,1-octene and 1dodecene were 39.8,38.8 and 37.5 min￣（-1）,respectively.The ratio of branched aldehyde to normal aldehyde was≥3.6.The organic products and the aqueous solution of catalyst could be easily seperated by decantution.The additive surfactant CTAB in a range of suitable concentration did not influence the seperation of two phases.更多还原
