摘　　要：利用含聚乙氧基链的季铵盐型离子液体与有机溶剂构成具有高温均相,低温分相功能的离子液体/有机两相体系,以1-十二烯为底物研究了在此离子液体/有机两相体系中三苯基膦三间磺酸钠(TPPTS)与RuCl3配合物催化的加氢反应.在优化反应条件下:十二烯/催化剂=1000(摩尔比),膦配体/RuCl3=5(摩尔比),反应温度80℃,压力2.0MPa,时间2h,产物十二烷收率可达98.7%.含有催化剂的离子液体经过简单相分离即可循环使用,经过10次循环催化活性无明显下降.An ionic liquid/organic biphasic system was developed by using polyether modified quarternary ammonium salts ionic liquid. This ionic liquid possesses a thermoregulated property＂mono-phase under high temperature; hi-phase under room temperature＂. The hydrogenation of 1-dodeeene catalyzed by TPPTS/RuCl3 complex has been studied in this new system. Under the optimal reaction conditions： S/Ru = 1000 （molar ratio） , TPPTS/ Ru = 5 （ molar ratio） , T = 80 ℃ ,p = 2.0 MPa and t = 2 h, the hydrogenation of 1-docecene reached＇98.7%. After reaction, the catalyst retained in ionic liquid can be easily recovered by phase separation at room temperature. The catalyst has been recycled for 10 times without significant decrease of the catalytic activity.
