| 摘 要： | 本文系统地研究了高级脂肪醇聚氧乙烯醚AEO型非离子表面活性剂醚键的氢碘酸断裂条件,并采用气相色谱分析法和容量分析法分别测定了样品的亲油基平均分子量及聚氧乙烯基的含量。根据AEO的环氧乙烷平均加成数与亲油基的平均分子量及聚氧乙烯基含量的定量关系,计算得出(EO)n。通过对测定结果重现性的考虑,证明了该方法的可靠性。

| Abstract: | This paper researches the cracking conditions in systematic for the ether bonds of the nonionic surfactant of the polyoxyethy iene ether from high fatty alcohol by hydroiodic acid. It determinates the average molecular weight of the hydrophobic group by GC and determinates the content of the polyoxyethylene group by titrinetry. The additive epoxy ethane average number is calculated based on the relation of the average number to the average molecular weight of the hydrophobic group and the content of the polyoxyethylene. The reasonableness of this method is proved on the inspection of reliability to the results |
