摘要
采用HP4890毛细管色谱柱、程序升温、FID检测,较好的分离了各种低加成数脂肪醇聚氧乙烯醚(AEO)样品中的各组分;使用GC-MS进行了样品中组分的定性,并经实验研究采用峰面积归一化法进行了组分的定量,较准确地计算出了各种样品AEO中游离脂肪醇质量分数及聚氧乙烯醚的环氧乙烷(EO)加成数分布。方法简便、快速,有较好的准确度和精确度。
GC(HP 4890) method has been developed for the separation and determination of lower distribution alkyl alcohol polyoxyethylene ether (AEO) . These AEO samples were capillary column, using temperture, FID detector. The components of AEO samples were identified by GC/MS. The free alkyl alcohol and ethoxymer distribution of polyoxyethylene of AEO sample were determined by normalization method. In comparing with previous methods, this method is simple, fast and more reproducible.
