| 摘 要： | 在由对甲基苯磺酸催化的1,3;2,4-二亚苄基山梨糖醇(DBS)合成的非均相缩醛化反应中,通过对反应规律的研究,以及运用Klymko等提出的一个分形介质上暂态反应的化学动力学模型,得到了适合该过程的山梨糖醇浓度与反应时间的关系,并验证了该过程模型的正确性,得到动力学方程ln1c=0.325 lnt 2.727。

| Abstract: | For the study of the kinetics of the heterogeneous acetalation process of the synthesis of 1,3;2,4-dibenzylidene sorbitol(DBS) on toluene-p-sulfonic acid catalyst the kinetic model of Klymko and others for the transient reaction on a fractal substrate was used.combining the experimental data and the moldel,the relation between the concentration of sorbitol and time was obtained,and the validity of the model for the process was proved.The kinetic equation for the reaction was:ln1c=0.325 lnt 2.727. |
