Smells nice, too: The cyclodehydration of citral is achieved by using rhodium nanoparticles dispersed in an imidazolium‐based ionic liquid. p‐Cymene, p‐α‐dimethylstyrene, and limonene are obtained with selectivity greater than 75 %. The interaction between the imidazolium cations and the metal nanoparticles results in an acidic catalyst, which plays a similar function as a mineral acid but has a one
气味也很好:柠檬醛的环化脱水是通过使用分散在咪唑基离子液体中的铑纳米颗粒实现的。获得对-甲基苯甲基,对-α-二甲基苯乙烯和li烯,其选择性大于75%。咪唑鎓阳离子与金属纳米颗粒之间的相互作用产生酸性催化剂,其起到与无机酸相似的作用,但是具有高一个数量级的活性。
