The ionic liquids potentialities to organize themselves in aqueous solution and produce aggregates were analyzed through the conductivity technique and after using a new mathematical model based on stochastic theories, to indicate the linearity change moment; it was possible to analyze the presence of these aggregates. It earns interest at science of colloids and interfacial chemistry due to the recognized ability of certain surfactant ionic liquids to reduce the surface tension of aqueous solutions and to aggregate in the form of micelles, even at low concentrations, allowing their use as stabilizing or destabilizing agents in homogeneous polymerization in water/oil emulsions. Within this context, this work aims to verify the possible micellar properties of the ionic liquids. Critical micellar concentration values for ions ammonium alkyl carboxylates were obtained. It was also shown that the CMC is directly related to the lipophilic groups of the cation and entropic factors.

水溶液中质子离子液体的胶束形成

通过电导技术分析了离子液体在水溶液中自行组织并产生聚集体的潜力，并使用了基于随机理论的新数学模型，以表明线性变化时刻。有可能分析这些聚集体的存在。由于某些表面活性剂离子液体具有公认的降低水溶液的表面张力并以胶束形式聚集的能力，即使在低浓度下也能用作稳定剂或去稳定剂，因此它在胶体和界面化学领域引起了人们的兴趣。在水/油乳液中进行均相聚合。在此背景下，这项工作旨在验证离子液体的可能胶束特性。获得了烷基羧酸铵离子的临界胶束浓度值。还表明，CMC与阳离子和熵因子的亲脂性基团直接相关。
