固体超强酸SO_4^(2-)/ZrO_2催化合成没食子酸正丁酯的研究

Performance of Solid Superacid SO_4 ^( 2-) /ZrO_2 in the Synthesis of n-butyl gallate

采用固体超强酸ＳＯ４２－／ＺｒＯ２催化合成没食子酸正丁酯的新工艺，探讨了合成反应条件对没食子酸正丁酯收率的影响。在优化反应条件下，没食子酸正丁酯的收率达到９３．４％。

A new process has been developed to synthesize n-butyl gallate from gallic acid and n-butanol by catalysis of solid superacid SO 4 2- /ZrO 2,and a study of the effect of reaction conditions in the yield of n-butyl gallate was also conducted.The yield of n-butyl gallate was 93.4% under the optimum reaction condition.
