采用季胺化反应—复分解或质子化两步法设计合成了系列阴离子为BF4-或CF3SO3-的咪唑类、吡啶类的功能化离子液体.系列功能化离子液体与三氟甲磺酸耦合催化1-丁烯/异丁烷的烷基化反应,并获得了C8选择性81.1%,TMP/DMH=8.36及RON值为95.3的良好催化效果,耦合催化剂在不降低催化活性的条件下可循环使用6次.
A series of functionalized ionic liquids with imidazoles and pyridines with anions of BF4- or CF3SO3- were designed and synthesized by quaternization reaction-metathesis or protonation. A series of functionalized ionic liquids were coupled with trifluoromethanesulfonic acid -butene / isobutane, C8 (selectivity 81.1%, TMP / DMH = 8.36 and RON 95.3) were obtained. The coupling catalyst could be reused without reducing the catalytic activity 6 times.
