摘要
本文报导了非离子表面活性剂聚乙氧基衍生物—羟值的一种新的分析方法。该方法突出的优点是短时间完成分析全过程 ,并获得与常规乙酸酐同样的分析效果 ,与标准样品进行比较实验 ,分析准确率可达 98%以上。
A new analysis method of hydroxyl value for non-ionic surface active agent was reported in the paper.The analysis period was shortened by using the new method and the analysis results of the new method were as accurate as those of eonventional methods.Aaccuracy of the result was more than 98% in comparison with standard samples.
