Abstract: An inclusion complex composed of Cinnamaldehyde andβ-cyclodextrin was prepared by solution-heating and the properties of the compound was investigated by using the IR absorption spectra, powder X-ray diffractometry and nuclear magnetic resoance. The kinetic behavior and process of thermal decomposition of the complex was studied by thermagravimetry. The decomposition reaction was controlled by random nucleation and subsequent growth mechanism (A1). Accordingly, kinetic equation can be deduced as, dα/dt=A·e-E/RT·(1-α). The kinetic compensation equation is lnA=0.19344E+2.19186.
