α-烯基磺酸盐(AOS)——一种广为应用的主表面活性剂(英)

α-Olefin Sulfonate—A Main Surfactant Used in Many Fields

研究了阴离子表面活性剂α－烯基磺酸盐的结构、性能。指出了影响α－烯基磺酸盐性质的因素：原料烯烃的碳链长度、中和用阳离子以及产品中烯基磺酸盐与羟烷基磺酸盐间的比率。报道了Ｃ１０～Ｃ１６ＡＯＳ在洗涤剂、个人保护用品中作为主表面活性剂的应用，其性能、价格比好。

The structure and performance of α-olefin sulfonate,one of main anionic surfactant is studied.The factors that influnce the performances of α-olefin sulfonate are:alkyl chain length of raw olefin,the cationic ions used in neutralization and the ratio between olefin sulfonate and hydroxyalkyl sulfonate.The application of C10～C16AOS used as main surfactant in the formulation of detergents and personal care products are also included.It is safe and good in performance/price.
