摘要
以[EMIM]Br合成了[EMIM]PF。及相应的PtB离子液体催化剂体系。IR、HPLC、tHNMR分析表明所合成的物质为目标离子液体；透射电镜（TEM）显示[BMIM]PF。中制备的PtB纳米颗粒粒径大小均匀，平均粒径大约10nm左右；在常压、240～300℃、油剂质量比为100：1的条件下进行甲基环己烷的脱氢反应，结果表明[BMIM]PE-PtB催化剂体系具有良好的脱氢活性。
Ionic liquid [EMIM]PF6 and the corresponding Pt-B in [EMIM]PF6 catalyst were synthe-sized from [-EMIM]Br. The IR, HPLC and 1H NMR results showed that the products are targeted i- onic liquids. TEM of the prepared nanometer PtB in [-EMIM]PF6 demonstrated a uniform particle size of 10 nm without apparent aggregations. The MCH dehydrogenation reactions were carried out at the normal pressure, and in the temperature range of 240 - 300 ℃ with the mass ratio of methylcyclohexane to Pt-B ionic liquid of 100 ： 1. [EMIM]PF6-PtB exhibited excellent dehydrogenation performance.
