摘要:摘要 已经合成了涂有固酸(例如zro2,Mo/zro2和w/zro2)的堇青石蜂窝结构.这些固酸催化剂也以粉末形式合成.通过bet,Nh3-Tpd/正丁胺反滴定,粉末xrd和sem等技术,分别对这些催化材料的物理化学性质,如表面积,表面酸度,结晶度和形貌进行了表征.这些催化材料的催化活性在酸催化的转酯化反应中被确定,该反应是将水杨酸甲酯与苯酚合成水杨酸苯酯(水杨醇).研究了mo或w离子在zro2上的浓度,催化剂的性质(涂层蜂窝结构还是粉末形式),反应温度,反应时间和催化材料的重复使用性对转酯化的影响.在zro2上增加mo或w离子的浓度以及在更高的反应温度下,观测到了二苯醚这一副产物的形成.催化材料的催化活性与其表面酸度和催化材料的晶相有关.转酯化反应也进行了水杨酸甲酯与苄醇或环己醇合成相应的水杨酸酯的反应.还提出了水杨酸甲酯与醇的转酯化可能的机理.与粉末形式的催化剂相比,蜂窝催化剂被发现是高效,环保,经济且可重复使用的催化剂.
