摘要
介绍了用丙酮(或乙醇)溶解酚醛树脂,用水蒸汽蒸吹出游离酚,然后用溴量法测定酚含量的方法。结果表明,该法的精度和准确度高,回收率为97%～102%,适用于酚醛树脂中酚含量的测定。
The determination method for phenol content is described. In the method acetone （or ethanol） is used to dissolve phenolic resin, free phenol is stripped out with water steam and bromometry is used to determine the phenol content. The result shows that the method has high accuracy and its recovery rate ranges from 97% to 102% and it is applicable to the determination of phenol content in phenolic resin.
