摘要 采用Æ3 mm×3 mm条状工业分子筛催化剂,在固定床管式反应器中考察了该催化剂在崁烯酯化制备乙酸异龙脑酯中的反应性能,建立了幂函数宏观动力学模型,运用最小二乘法进行动力学模型参数估计。结果表明,崁烯酯化制备乙酸异龙脑酯的表观活化能(Ea)为47.225 kJ/mol,对崁烯和乙酸的反应级数分别为0.15和0.5。预测值与实验值能较好地吻合,表明动力学模型是适用的。

Abstract:The performance of esterification of camphene for isobornyl acetate over self-prepared strip catalyst with industrial original particle size Æ3 mm×3 mm in a fixed bed tube reactor was studied. Macro-kinetics for esterification of camphene were obtained from the experimental data under different conditions using the power-low kinetics model with the nonlinear least squares method. The results showed that the apparent activation energy for esterification of camphene was 47.225 kJ/mol, and the reaction orders for camphene and acetic acid concentration were 0.15 and 0.50, respectively. The residual error distributions and the statistic tests showed that the proposed macro-kinetic models are reliable and adequate.
