- W2394223831 abstract "In order to study the interaction between β-cyclodextrin and substrate or product, which is quite helpful for mastering chemical reaction mechanism promoted by β-cyclodextrin, β-cyclodextrin was used as catalyst for the oxidation of methyl phenyl sulfide in water, and it was observed that the oxidation product, methyl phenyl sulfone, can exist stably in the cavity of β-cyclodextrin and form inclusion. Various characterization methods including 1H-NMR, TG-DSC and FT-IR were adopted to analyze the interaction between β-cyclodextrin and methyl phenyl sulfone. It shows that the stable inclusion of β-cyclodextrin and methyl phenyl sulfone with molar ratio of 1:1 can be automatically formed in water (the stability constant of the inclusion, Ka, is 5015 and the standard Gibbs function of molar reaction, △γG_m~θ (289K), is –21.109 kJ·mol-1). The informations of inclusion characterized by circular dichroism and fluorescence spectrum are different from that of β-cyclodextrin obviously. FT-IR analysis exhibits that the inclusion formed by methyl phenyl sulfone entering from the narrow mouth of the β-cyclodextrin is more stable than that formed by entering from the broad mouth." @default.
