Isolongifolenone was synthesized from isolongifolene,and in order to optimize the catalytic oxidation condition,orthogonal experiment was conducted with oxygen volume fraction,gas flux, reaction time and reaction temperature chosen as factors.The optimal conditions for industrial production were determined by using the Minitab software analysis as follows,oxygen volume fraction 35%,gas flux around 60mL/min,reaction temperature 60℃ and reaction time 8 hours,and the corresponding conversion rate and yield were 61.79%and 55.49%respectively. In addition,presence of water in the reaction system was investigated,and the results showed that water had a great influence on reaction conversion rate and yield of product. The kinetics of the reaction process was studied. The oxidation reaction was first-order kinetic process with activation energy (64.92kJ/mol). The research data would provide the foundation for industrial production of isolongifolenone.
