An inclusion compound of p -azidobenzoic acid with β-cyclodextrin (β-CD) was prepared and characterized by thermogravimetry, IR, ~1H NMR and UV spectroscopies. The thermal stability of p-azidobenzoic acid was significantly improved after inclusion, and the decomposition temperature difference between the pure p-azidobenzuic acid and that in conclusion compound was +115 ℃. By using data of UV spectroscopy, the binding constant of the inclusion compound was estimated to be (7933 ± 192) L·mol~(-1).
