1-氧代-1-[（4-氟烷基）苯基]-2-链烷磺酸钠（FCm-HCn）是一种氟碳-碳氢混合表面活性剂，在固体表面上具有特殊的吸附行为。本文研究了混合表面活性剂对油性化合物的增溶作用。还比较了混合表面活性剂与1-（4-烷基苯基）-1-氧代-2-烷磺酸钠（HCm-HCn）（双链型表面活性剂，其中混合表面活性剂中的氟碳链被烃链取代）的增溶行为。结果发现，FCm-HCn亚胶束可以溶解氟代苯和全氟苯等碳氟化合物以及烃（2-萘酚）。这些油性化合物的增溶量以2-萘酚<氟苯<全氟苯的顺序增加，显示混合表面活性剂增溶含氟油性化合物的高能力。另一方面，HCm-HCn只能在非常小的范围内增溶碳氟化合物。
Sodium 1-oxo-1-[(4-fluoroalkyl)phenyl]-2-alkanesulfonates (FCm−HCn), fluorocarbon−hydrocarbon hybrid surfactants, exhibit a peculiar adsorption behavior on solid surfaces. This report dealt with an investigation on the solubilization of oily compounds into admicelles of the hybrid surfactant. Comparison was also made between the solubilization behavior of the hybrid surfactant and that of sodium 1-(4-alkylphenyl)-1-oxo-2-alkanesulfonates (HCm−HCn), double chain-type surfactants, in which the fluorocarbon chain in the hybrid surfactant is replaced by a hydrocarbon chain. As a result, FCm−HCn admicelles were found to solubilize fluorocarbons such as fluorobenzene and perfluorobenzene as well as hydrocarbon (2-naphthol). The amount adsolubilized for these oily compounds increased in the order 2-naphthol < fluorobenzene < perfluorobenzene, showing a high ability of the hybrid surfactant to solubilize oily compounds containing fluorine. On the other hand, HCm−HCn could solubilize fluorocarbons in only very sma...
