摘　　要：环糊精是由不同的β-吡喃葡萄糖单元环状排列而成的圆锥状中空桶形分子，其独特的外亲水、内疏水结构决定了其特殊的性能。目前环糊精及其衍生物在医药、水处理方面应用广泛，但在造纸湿部中的应用很少。该文主要介绍了环糊精的结构、环糊精衍生物和环糊精聚合物的合成方法及其种类；综述了环糊精衍生物在废纸造纸湿部中的应用现状，预测了其在阴离子垃圾捕捉剂和助留助滤剂中的广阔应用前景。Cyclodextrins, composed of various D-glucopyranose structural units, are conically shaped molecule with tubular configuration derived from cyclic arrangement of the D-glucopyranose units. Their unique structures of exohydrophilicity and endo-hydrophobicity determine their particular performances. At present cyclodextrins and their derivatives are widely applied in medicine, water treatment, while their application in papermaking wet end is rare. This paper mainly introduces structures of cyclodextrins, synthesis methods of cyclodextrin derivatives and cyclodextrin polymer, and their types, reviews the application status of cyclodextrin derivatives in waste papermaking wet end, and predicts its broad application prospect in anionic trash catcher aid and retention agent.
