摘　　要：围绕着功能化酸性离子液体这一主题,对新型Lewis,Bronsted酸性离子液体、离子液体的酸性测定以及酸性离子液体在异丁烷/丁烯烷基化反应中的应用进行了介绍和评述;提出了由新型酸性离子液体的合成、其酸性的表征及其催化性能的评价3方面有机地构成了研发酸性离子液体参与的工艺技术的良性过程;明确了“功能化”的涵义;展望了酸性离子液体巨大的工业应用前景。Focusing on functionalized acidic ionic liquids,researches on syntheses of Lewis,Bronsted acidic ionic liquids,determination of acidity of ionic liquids and application of acidic ionic liquids to alkylation of isobutane with butene were reviewed. The three topics reviewed, i. e. synthesis of novel acidic ionic liquids, acidity characterization and evaluation of their catalytic activity constitute a sustaining methodology to develop industrial processes involving acidic ionic liquids. The connotations of 'functionalized' are given. Finally the great potential of industrial application of acidic ionic liquids is discussed.
