研究了水相中β-环糊精与N-羟基邻苯二甲酰亚胺(NHPI)的包合作用,通过Hildebrand-Benesi法确定其包合比为1:1,并结合红外光谱辅助说明,同时计算出25℃时包合稳定常数为1 412L/mol,计算出热力学常数AH、△S、△G,初步探讨了超声波对包结产率的影响规律.%The study on inclusion between β-cyclodextrin and NHPI in aqueous solution has been made.The ratio of inclusion 1 ∶ 1 was calculated by the method of Hildebrand-Benesi, which was tested by IR.The inclusion constant was also calculated, which was 1 412 L/mol. The thermodynamic parameters for inclusion reaction such as △H,△S,△HG were derived from the inc1U8ion constants at different temperatures. We have a simple description on the inclusion yield under the supersonic condition.
