| 摘 要： | 以固体酸SO_4~(2-)/TiO_2-SnO_2-ZnO为催化剂,丙烯酸和1,6-己二醇为原料,考察了催化剂加量、转速以及催化剂粒径对酯化反应速率的影响。在消除内外扩散影响的前提下,建立了固体酸催化合成1,6-己二醇二丙烯酸酯拟均相反应动力学模型,得到了相应的动力学方程参数,动力学模型预测的结果与实验结果吻合良好。

Kinetics of Synthesis of 1,6-Hexanediol Diacrylate over SO42-/TiO2-SnO2-ZnO Solid Acid |

| Abstract: | The esterification of acrylic acid and 1,6-hexanediolcatalyzed bythesolid acid SO42-/TiO2-SnO2-ZnO was studied and the effects of the catalyst dosage, stirring speed, particle size were investigated. The corresponding intrinsic kinetic parameters were obtained and a kinetic model of the abovepseudo-homogeneous esterification was established under the conditions of eliminating internal and external diffusion effects. It was found that the kinetic model predictions were in good agreement with the experimental results. |
