离子液体作为一类新型的环境友好的“绿色溶剂”,具有许多独特的性质,在很多领域有着诱人的应用前景.但是具有表面活性的离子液体很少报道.以不同链长溴代烷烃(C10～C18)与N-甲基-2-吡咯烷酮进行季铵化反应得到一系列具有表面活性的新型离子液体.这类含有吡咯烷酮基团的离子液体不但具有离子液体的性质,同时也具有优良的表面活性和良好的生物相容性.
As a new type of environment-friendly “green solvent”, ionic liquids have many unique properties and attractive prospect in many fields, however, ionic liquids with surface activity are seldom reported.It has been reported that ionic liquids with different chain lengths of brominated alkanes C10 ~ C18) with N-methyl-2-pyrrolidone to obtain a series of novel ionic liquids with surface activity.The ionic liquids containing pyrrolidone groups not only have the properties of ionic liquids, but also have excellent Surface activity and good biocompatibility.
