【摘要】 以没食子酸和正丁醇为原料 ,采用一水合硫酸氢钠作催化剂合成没食子酸正丁酯 .研究了一水合硫酸氢钠用量、正丁醇用量和反应时间对没食子酸正丁酯收率的影响 .当没食子酸、正丁醇和硫酸氢钠的物质的量比为 1 :1 5 :0 .0 34,回流分水 5 h,酯收率达 92 .3% .更多还原

【Abstract】 n Butyl gallate was synthesized by gallate acid and n butyl alcohol with sodium bisulfate as catalyst.The effects of the amount of sodium bisulfate monohydrate,the amount of n butyl alcohol and reaction time on the yield of n butyl gallate have been investigated.The yield of the ester could reach 92.3% under amount of substance ratio of gallate acid,n butyl alcohol and sodium bisulfate were 1∶15∶0.034,refluxing and water segregation for 5 h.更多还原
