摘要： 首次在亲水性离子液体[Rmim][p-CH3C6H4SO3](1-烷基-3-甲基咪唑对甲苯磺酸盐, R = 甲基、乙基、正丁基、正己基和正辛基)中, 以水溶性的[RuCl2(TPPTS)2]2 (TPPTS: 间磺酸钠基三苯基膦)为催化剂, 分别考察了温度、压力、不同的离子液体、水和碘的加入等因素对喹啉加氢反应的影响. 在100 oC和氢气压力为3.0 MPa时, 喹啉加氢生成1,2,3,4-四氢喹啉的选择性超过99%, 转化率达到95.3%. 利用环己烷萃取反应产物, 即可实现催化剂与产物的分离, 催化剂循环使用6次后反应的转化率仍可达86.0%.

Abstract: The catalyst [RuCl2(TPPTS)2]2 was used in the regioselective hydrogenation of quinoline in [Rmim][p-CH3C6H4SO3] with high conversion and selectivity. The products can be easily separated from the catalyst immobilized in ionic liquids by simple extraction with cycohexane. The conversion reached 86.0% when the catalyst was reused 6 times.
