摘要: 本文研究了固体酸对醇酸树脂缩聚酯反应的催化作用,讨论了催化剂的表面酸度、制备条件及反应物分子构型等对催化聚酯反应的影响。在接近生产条件下研究了醇酸树脂聚酯反应动力学,发现多相酸催化聚酯反应与均相酸催化聚酯反应具有相似的动力学规律。

Abstract: The catalytic behaviour of some solid acids on the polyesterification reaction was investigated. The effect of surface acidity, conditions of catalyst preparation and molecule structure of reactants on the polyesterification of alkyd resins was discussed. It was found that in conditions near to that for Industrial preparation the kinetics of the heterogeneous catalytic polyesterification of alkyd resins appeared the same as in the case of homogeneous reaction.
