摘要
采用酰氯化-重结晶-水解-酸析的方法实现了对2,6-萘二甲酸的纯化,提纯产物结构通过红外光谱、核磁谱图确定其为2,6-萘二甲酸,并通过对提纯产物酸值的测定,确定提纯后的2,6-萘二甲酸纯度达到99.73%,达到聚合级要求.该方法反应条件温和,操作简单,比较适用于工业化生产.
In this article, 2,6-Naphthalene dicarboxylic acid was purified by the method of Chlorization recrystallization-hydrolyticaction-acidout; structure of product was analyzed through the FT-IR spectrum and 1H NMR. The product was ascertained as 2,6-Naphthalene dicarboxylic acid. Purity of product was confirmed by the measure of acid number of product, which meets the requirement of polymerization. Its reaction conditions were moderate and its operation was simple, so it was suitable for use in industrial production.
