摘要
对非离子表面活性剂十二醇聚氧乙烯醚(AEO)产品的内在质量——分子量分布的测定方法进行了研究.首先将AED产品进行三甲基硅烷化预处理,采用OV- 17固定相进行气相色谱分析,以标样和文献对照进行了定性与定量,测定结果可以很好地反映出AEO产品的分子量分布.
A method for determination of the molecular weight distribution, which shows the internal quality of AEO products, of nonionic surfactants of dodecyl polyoxyethylene ether(AEO) was studied. AEO sample was pretreated by trimethyl silanization and analyzed by gas chromatography on OV-17 stationary phase. Identification and quantification were carried out based on standard sample and reference. The result was satisfactory to show the molecular weight distribution of AEO products.
