本文讨论了催化剂酸度,载体的比表面、孔径等因素对催化聚酯化活性的影响,在此基础上提出了醇酸聚酯化反应的Lewis酸催化作用机理,有关反应的动力学行为也进行了探讨并给出了相应的表观活化能。
In this paper, the effects of catalyst acidity, specific surface area and pore size of catalyst on the catalytic polyesterification activity were discussed. The Lewis acid catalysis mechanism of alkyd polyesterification reaction was also proposed, and the kinetic behavior of the reaction was also carried out Explore and give the corresponding apparent activation energy.
