以柠檬酸/Hβ沸石（CA/Hβ）为催化剂，研究了反应温度、反应物浓度、催化剂负载量和转速对芝麻油体系芝麻素转化反应动力学的影响。建立了芝麻素转化的动力学模型。该动力学模型与芝麻素和细辛脂素的实验浓度拟合良好（分别为= 0.93和= 0.97）。芝麻素的转化为吸热反应（△HrIso = 34.578kJ/mol）。CA/Hβ催化剂经焙烧后易于再生，重复使用后催化活性无明显损失。了解芝麻素的转化规律，对指导生产，提高芝麻油的营养价值具有重要意义。本研究为CA/Hβ催化芝麻油合成细辛脂素的放大奠定了基础。
In the present work, effects of reaction temperature, reactant concentration, catalyst loading, and rotation speed on the kinetics of sesamin conversion in a sesame oil system were studied by using citric acid loading on Hβ zeolite (CA/Hβ) as a catalyst. A kinetic model was built for sesamin conversion. The kinetic model fits correctly the experimental concentration of sesamin and asarinin ( = 0.93 and = 0.97). The sesamin conversion is an endothermic reaction (△HrIso = 3 4.578kJ/mol). The CA/Hβ catalyst could be easily regenerated by calcination, and there was no obvious loss of catalytic activity when reused. Knowledge of the sesamin conversion is of great significance for guiding production and improving the value and nutrition of sesame oil. In a word, this study lays the foundation for the scale-up of the production of asarinin from sesame oil using CA/Hβ as the catalyst.
