✦ Synopsis

The formation of mesomorphic (liquid crystalline) systems by highly concentrated solutions of dioctyl sodium sulfosuccinate in an. homologous series of five even-numbered chain length !-aliphatic hydrocarbon solvents was studied. It was determined that dioctyl sodium sulfosuccinate concentration, solvent chain length. and temperature sigrlificantly affect the formation ,of a mesomorphic phase. At constant temperature, the concentration of pioctyl sodium sulfosuccinate required to produce a mesomorphic phase increased as the solvent chain length increased from octane to dpdecane and then decreased to hexadecane. At constant diatyl sodium sulfosuccinate concentration in each of the five solvents, the mesomorphic-to-isotropic phase transition temperature reached a minimum at dodecane; however, the phase transition temperatures for dioctyl sodium sulfosuccinate systems in tetradecane and hexadecane were higher than those for decane and octane, respectively.
