邻二甲苯法制苯酐催化剂的研究进展

摘要

从催化剂各组分的作用、反应机理、工艺流程、苯酐生产技术的发展近况等方面，对近年来国内外邻二甲苯法制苯酐催化剂研究开发情况作了比较详细的介绍．对催化剂的研究方向和发展前景进行了探讨．%This paper makes a detailed introduction about the research development of making phthalic anhydride catalyst by O-xylene at home and abroad in recent years from several aspects, such as the function of each component of catalyst, reaction mechanism, process and phthalic anhydride producing skill and so on. Besides, the research trend and prospects of catalyst are also discussed in this paper.
