摘要
用溶剂法对倍子工业单宁酸进行了提纯研究，通过对萃取温度、搅拌时间和粒度等条件的探索及对几种常用有机溶剂的对比和复配试验，结果所得工业单宁酸的纯度由７８％～８０％提高到９２．７６％，产品颜色变浅。
The test is to purify the solvent extraction proces of industrial tannic acid. The test has been proceed by extractive temperature、crutchal time、mesh size and compounds of some ordinary organic solvents used. The result has shown that the content of industrial tannic acid was risen from 78%～80% to 92.76%, colour of products was changed into light and mass of products is stable.
