Abstract

Abstract : In this study, inclusion complex of cis -jasmone in β-CD (β-CD-CJ) was synthesized to improve cis -jasmone stability. Abstract : In this study, inclusion complex of cis -jasmone in β-CD (β-CD-CJ) was synthesized to improve cis -jasmone stability. The structure and thermal kinetics of the inclusion complex was investigated by Fourier transform infrared spectroscopy (FTIR), thermogravimetric analysis (TG) and differential scanning calorimetry (DSC). DSC studies showed that the stability of cis -jasmone after β-cyclodextrin encapsulation was improved. The dissociation kinetics of β-CD-CJ at different heating rates was studied by TG, and the activation energy E of β-CD-CJ thermal decomposition kinetic parameters was defined by Flynn–Wall–Ozawa method. The results showed that the average activation energy E was 121.16 kJ mol −1 .
