在298.15K下，研究了氯化烷基吡啶（C（n）PC，n=14，16）与Triton X-100的混合物在整个摩尔分数范围内的反应。对于每种混合物，从表面张力测量获得CMC。为了估计相互作用参数值（β）、单体浓度的计算和混合胶束中单个表面活性剂的摩尔分数，通过应用规则溶液理论使用CMC数据。结果表明，随着C（n）PC链长的增加，阳离子表面活性剂在混合胶束中的优先掺入作用增强。的大值|Delta G（o）|证实了C16 PC和Triton X-100的混合胶束是显著有利的。
The mixtures of alkylpyridinium chloride (C (n) PC, n=14, 16) and Triton X-100 were studied over the entire mole fractions at 298.15 K. For each mixture, CMC was obtained from surface tension measurements. To estimate the interaction parameter values (beta), the calculation of the monomer concentrations and the mole fractions of the individual surfactants in the mixed micelles, the CMC data were used by applying the regular solution theory. The obtained results showed that the increase of the chain length of C (n) PC led to the stronger preferential incorporation of cationic surfactant in mixed micelle. The large values of |Delta G (o) | confirmed that mixed micelle of C16PC and Triton X-100 was significantly favorable.
