| 摘 要： | 提出了一种测定液体稳定剂中的游离苯酚含量的化学分析方法。其原理基于苯酚能与溴定量反应。具体的步骤是,向液体稳定剂中加入定量的溴,用定量的碘化钾与溴化反应后剩余的溴反应,再用Na2S3O3标准溶液滴定反应生成的碘。根据Na2S3O3标准溶液用量,可以计算出液体稳定剂中游离苯酚的含量。

| Abstract: | A chemical analysis method for determination of the free phenol content in liquid stabilizer was suggested. The printipal of it is based on the phenal can react with bromine quantatively . The steps of this method are,first to add a quantative bromine in the liquid stabiliger,then added a quantafive KI reacts with the remained bromine after bromination,the I2 produced in this reaction is titrated by Na2S2O3 standard solugion According the consumpution of Na2S3 standard solution,the free phenol content in liquid stabilizer can be calculated. |
