摘要
研究了硅钨杂多酸对水杨酸正丁酯合成的催化性能,得出的最佳工艺条件为:n(水杨酸):n(正丁醇)=1:2、正丁醇为带水剂,催化剂硅钨杂多酸1.5g,回流反应4h,收率可达94.6%,并证明了硅钨酸为该反应良好的催化剂,具有催化活性高,化学稳定性好,重复使用性能佳,无三废排放等优点。
The use of Si - W heteropoly acid as catalysis of n - Butyl Salicylate is studyed. The best reaction conditions are： n （Salicylic acid） ：n（n- butyl alcohol） = 1：2, n-butyl alcohol as water carrier, 1.5g Si- W heteropoly acid as catalyst, refluxing for 4 hr, the yield 94.6 %. It is proved that Si - W heteropoly acid is a good catalyst of the reaction, with high activity, good chemical stability, good repeatability and little waste discharged.
