1. 毕业设计(论文)的内容和要求

苯二酚是重要的化工产品,用途极其广泛.目前制备苯二酚的研究大多集中在由过氧化氢直接氧化苯酚的工艺路线上,该路线流程简单,反应条件温和,过氧化氢价廉,氧化副产物(水)无污染,符合绿色化学的要求,是目前最理想的生产苯二酚的方法.在分子筛及多孔材料中引入金属活性组分,将其用于以双氧水为氧化剂的苯酚经基化反应所涉及的多孔材料种类繁多,如HMS , TS-1 ,MCM-41 , MCM-48 , MOR3等.纳米四元水滑石具有较好的孔道结构,是石油化工领域重要的催化剂,但将其用于以双氧水为氧化剂、水为溶剂的苯酚氧化反应体系的研究较少.本论文以四元纳米水滑石为研究对象,分别采用浸渍法、沉淀法及离子交换法制备了系列催化剂,系统考察了制备方法、活性组分以及助剂等因素对苯酚氧化反应性能的影响.
