摘　　要：本文用裂解色谱法对脂肪醇聚氧乙烯醚、烷基硫酸盐和一些季铵盐表面活性剂的疏水基进行了分析。说明了裂解条件和裂解产物，介绍了鉴别疏水基和测定烷基同系物分布的方法。与其它方法相对照，测定结果相符。方法简便、快速、样品用量少。Abstract: The pyrolysis gas chromatography is used for analysis of hydrophobic groups of polyoxyethylated alcohol, alkyl sulfate and some quaternary ammoniun salt surfactants. The pyrolytic conditions and pyrolysis products are described. The methods for identifacation of hydrophobic groups and determination of alkyl homolog distributions are presented.The results obtained are in agreement with those by other methods.The method is simple as well as rapid and sample size used is small
