临界胶束浓度和铜(II)肥皂溶液的电导行为在benzene-methanol混合物由以下方程在不同温度(40、45、50和550 c):对数μ= A + B c和B是常数,c浓度的铜皂在g。摩尔/升和μ是分子的导电性。日志μ的值和B通常随着温度增加。日志μ的值和B也会增加与增加系统中甲醇的体积百分比。上述系统遵循克劳斯和布雷类型表达式和数据显示,总体而言,离解常数增加,限制摩尔电导随温度高达50%的甲醇溶剂混合物。The work has been extended to collect thermodynamic parameters such as the heat of dissociation, H0, to enable the behaviour of soap solutions to be better understood. In regard to chain length of the soap, the cmc values are in the order: Caprate < Caprylate. CMC increases with the increase in the methanol percent in the solvent mixture. The results confirm that the change in the nature of micelles from hydrophilic oleomicelles to lipophilic hydromicelles occurs in solutions at about 50% methanol.
