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.

Stability of Conjugated Dienes
A comparison of the enthalpies of hydrogenation of dienes reveals that conjugated dienes release less heat on hydrogenation, rendering them more stable than their nonconjugated analogs.
Stability of Substituted Cyclohexanes
The two chair conformations of cyclohexanes undergo rapid interconversion at room temperature. Both forms have identical energies and stabilities, each comprising equal amounts of the equilibrium mixture. Replacing a hydrogen atom with a functional group makes the two conformations energetically non-equivalent.
