铁系固体酸催化剂的制备及催化合成水杨酸酯

Preparation and Catalyst of Activity of Ferric Solid Acid in Synthesizing Salicylate

制备了铁系固体酸催化剂 (Ⅰ )并将其用于催化合成水杨酸酯 ,优化了反应条件 :当Ⅰ用量为投料质量的6.1 % ,mol酸∶mol醇 =1∶4 ,适当提高反应温度 ,合成水杨酸戊酯的反应时间可缩短至 3h ,产率达 91 .3 %。合成其它水杨酸酯时也取得很高的产率。通过对比 ,Ⅰ的催化酯化能力优于Fe2 O3/SO2 4 固体超强酸催化剂 ,套用

The man-made ferric solid acid were used as a catalyst for the synthesis of four salicylates with a yield of 91.3%(pentyl salicylate), 90.7%(butyl salicylate), 92.3%(isopentyl salicylate), and 92.0%(n-octyl salicylate) respectively.
