摘要：

Ethoxylated surfactants have been reported to show improved interfacial tension and calcium tolerance properties, even though the mechanism by which ethoxylates influence interfacial phenomena are not completely understood. The impurities present in technical grade ethoxylated sulfonates place a major hurdle in studying this type of surfactants. A technique based on flash chromatography was therefore developed for separating them and the collected fractions were characterized using HPLC and NMR. Adsorption studies showed the nonionic impurities to enhance the adsorption of as received and purified ethoxylated sulfonate on alumina in the premicellar region. This work is pertinent to micellar flooding in petroleum.
