The phase behavior of carboxylic acid/alkylamine mixtures in H2O is largely dictated by a proton transfer from the acid to the amine, which will lead to charged species. If the distribution of C atoms is unequal between the acid and the amine, the result will be an ionic surfactant with an organic counterion. The phase diagram for the ternary system HOAc-dodecylamine-H2O at 298.2 K was determined Dodecylamine forms a lamellar phase with H2O, but when HOAc is added up to an equimol. ratio between acid and amine, 3 new phases appear. These phases are an isotropic solution phase, a hexagonal liquid crystalline phase, and a cubic liquid crystalline phase. These 3 phases are not able to incorporate any excess amine. The solution phase shows the existence of micelles, which are spherical at high dilution, but show an elongation close to the phase border to the hexagonal phase.
