以没食子酸与乙酸酐反应,生成三乙酰没食子酸(TAGA),再与SOCl2反应,制备目的产物三乙酰没食子酰氯(TAGC).结果表明,TAGA合成最佳原料摩尔比为1∶4∶4,产率基本在87％左右,TAGC合成最佳原料摩尔比为1∶3,产率基本在95％左右.实验方法稳定可行,且操作简单,污染小,可用于工业生产.%With gallic acid and acetic anhydride react to generate three acetyl gallic acid (TAGA) and reacted with SOCl2 prepare purpose product of (TAGC). Results showed that the besl material ratio of TA GA synthesis 1:4:4 .yield was about 87% ,the best material ratio of TAGC synthesis 1 : 3 .yield was a-bout 95%.The experimental method is reliable and practical,easy operation,low pollution,and can be used in industrial production.
