Huang, Wen published the artcileAggregation behavior of dodecylammonium carboxylates in carbon tetrachloride, HPLC of Formula: 2016-56-0, the publication is Huaxue Xuebao (1996), 54(10), 943-948, database is CAplus.
The aggregation of dodecylammonium acetate (DAA), dodecylammonium propionate (DAP) and dodecylammonium butyrate (DAB) were studied by an iodine spectrometric method and by H2O solubilization. The (cmc)I determined by the I method are 2.0 ¡Á 10-4, 2.2 ¡Á 10-4, and 4.3 ¡Á 10-4 M, resp.; the (cmc)W determined by H2O solubilization are 2.0 ¡Á 10-3, 3.5 ¡Á 10-3, and 10.5 ¡Á 10-3 M, resp. The (cmc)I are lower by 1 order of magnitude than the corresponding (cmc)W. The reason is probably that aggregates with low aggregation number which begin to form at (cmc)I cannot solubilize H2O. The H2O solubilization starts only when the aggregation number of reverse micelles is high enough, which occurs at (cmc)W (a concentration much higher than (cmc)I). These experiments show that reverse micelles of DAA, DAP, and DAB are able to solubilize ¡Ü 4.3, ¡Ü 9.4, and ¡Ü 13.5 mols. of H2O per surfactant mol., resp. According to a simplified spherical reverse micelle model, the aggregation numbers of the DAA, DAP, and DAB reverse micelles which solubilize the limiting amount of H2O are 24, 122, and 252; the radii of the H2O pools are 0.90, 2.02, and 2.90 nm, and the radii of the free H2O pools are 0.33, 1.68 and 2.58 nm, resp.
