Abstract

Size and shape of micelles of Na and K salts of (tripentylmethyl)benzenesulfonic acid in n-heptane were determined from light scattering and sedimentation. These systems behave quite differently from most aqueous micellar systems, which entails special problems in the interpretation of the experimental results. The micelle size depends strongly upon soap concentration and temperature and upon the nature of the cation.

The behavior of the potassium sulfonate micelles can be reasonably described in terms of a model theory, which theory, however, does not hold for the sodium soap.

正庚烷中苯磺酸钠和(三戊基甲基)钾的胶束形成
用光散射法和沉淀法测定了正庚烷中(三戊甲基)苯磺酸钠盐和钾盐的胶束大小和形状。这些系统的行为与大多数水性胶束系统完全不同,这在解释实验结果时带来了特殊的问题。胶束的大小在很大程度上取决于肥皂的浓度、温度和阳离子的性质。磺酸钾胶束的行为可以用一种模型理论来合理地描述,然而,这种理论并不适用于钠皂。
