| Abstract: | The synthesis and characterization of the basic ionic liquid,1-butyl-3-methylimidazolium imidazolide (Bmim]Im),were reported intensively.Bmim]Im has strong basicity and relatively good thermal stability,and it was used as a novel catalyst for the Knoevenagel reactions in aqueous media.Bmim]Im acted as both a base catalyst and a phase transfer catalyst in the Knoevenagel reaction.In addition,Bmim]Im together with aqueous media had good recycle ability.Aqueous media,low catalyst concentration,simple separ... |
