本文以β－环糊精为主体，研究了它对２，４－二硝基苯酚、对氯苯酚和２，４－二氯苯酚的包络特性，作出了相应的包络特性曲线，探讨了浓度、ｐＨ 值对包络特性的影响。结果表明：β－环糊精对２，４－二硝基苯酚、对氯苯酚和２，４－二氯苯酚的包络物组成均为１∶１，包结常数分别为１．０×１０５、２．８×１０２、２．５×１０２，浓度和ｐＨ 值对包络特性有显著影响。
In this paper, β-cyclodextrin as the main body, its 2,4-dinitrophenol, p-chlorophenol and 2,4-dichlorophenol characteristics of the envelope, the corresponding envelope characteristics curve, discussed Effect of concentration and pH on the enveloping properties. The results showed that the inclusion complex of β-cyclodextrin for 2,4-dinitrophenol, p-chlorophenol and 2,4-dichlorophenol was 1: 1 and the inclusion constants were 1.0 × 105 , 2.8 × 102,2.5 × 102, the concentration and pH value of the envelope characteristics have a significant impact.
