Abstract: The Thermal Decomposition Kinetics of β - cyclodextrinand Vanillin inclusion complex has been studied by using non - isothermal thermogravimetry. The experiment result showed that reaction order of thermal decomposition of β - cyclodextrin and vanillin was of the first order. The average activation energy of the themal decomposition was 180. 28kJ/mol. The preexponential factor A was 9. 858 × 1019. The kinetic compensation e-quation was logA = 0. 0897E + 2. 4665. The enthalpy change was △Hr = 85. 90kJ/mol and entropy change △Sr = 0. 146kJ/mol•K.
