摘　　要：温控相转移膦配体及其催化作用Ⅳ．三┐对羟聚氧乙烯醚苯基膦铑配合物催化苯乙烯两相氢甲酰化反应研究＊王艳华１蒋景阳１何２金子林＊＊１（１大连理工大学化工学院，大连１１６０１２；２天津大学Ｃ１化工国家重点实验室，天津３０００７１）关键词膦铑配合物，苯乙烯...Nonionic water soluble phosphine rhodium complex was prepared in situ by the reaction of [JJ1,0;4,0] P OCH 2CH 2) n OH] 3 (TPPP) with RhCl 3·3H 2O. The catalytic activity and selectivity of TPPP/RhCl 3·3H 2O for styrene hydroformylation are studied in biphase catalytic system. In addition, effect of reaction temperature, pressure, organic solvent and V (water)/ V (styrene) was investigated. The results showed that the reaction took place mainly in the organic phase at higher temperature (90℃). Under the condition of 90℃ and 6 0 MPa the reaction was carried out in toluene for 3 5 h, the conversion of styrene is 98 0%, aldehyde yield is 94 4%, iso/normal molar ratio of aldehyde is 1 4.
