Study of inclusion complex of beta-cyclodextrin and nitrobenzene.
نویسندگان
چکیده
beta-cyclodextrin can react with nitrobenzene to form an inclusion complex which is characterized by (1)H NMR and powder X-ray diffractometry. The ratio of beta-CD to NB in inclusion complex is determined as 1:1. At 25 degrees C, the dissociated constant, K(D), of the inclusion complex is measured as 6.5 x 10(-3) M in neutral solution (pH=7.0), but in alkali (pH=13.5), K(D) is 3.2 x 10(-2) M which is much larger than that measured in neutral.

The adsorption of nitrobenzene on active carbon was researched. The experimental results shown the adsorption of nitrobenzene on active carbon can be described by Freundlich's adsorption model. On the other hand, beta-cyclodextrin (beta-CD) and hydroxypropyl-beta-cyclodextrin (HP-beta-CD) can react with nitrobenzene to form inclusion complex, which will enhance the aqueous solubility of nitrobe...
