| Popis: | The general phase behavior of selected alkyl benzene sodium sulfonates was studied with the aim of determining specific factors which will enhance solubilization of oil and/or water in microemulsions. In pursuing this, it was discovered that decreasing the branching of the surfactant tail shifts the system to lower optimum ACN, narrows the width of the three-phase region, increases the solubilization parameter, and decreases the interfacial tension for systems in the optimum state, all other system variables remaining constant. Specifically, it was found that the width of the three-phase region was in simple inverse proportion to the solubilization parameter, and a previously proposed mathematical relationship between interfacial tension and solubilization was verified. Additionally, it was found that the alkyl chain tail length and the position of the benzene ring attachment exhibit linear mixing rules for optimum systems when the surfactants are mixed on a mole fraction basis. |
