Sažetak

The molecular arrays in crystalline n-alkylbenzenesulfonates (CS-C12) were determined by X-ray diffraction and found to be lamellar bilayers with the basic lamellar thickness of 30.1-36.9 A for single-tailed, and 22.25-30.0A for C12 double-tailed surfactants, depending on the length of surfactant molecule. In the colloid dispersions of metal dodecylbenzenesulfonates as well as in the systems of double-tailed C12-isomers, microscopic investigations of liquid crystal textures showed the characteristic lyotropic nematic, lamellar, pseudo-isotropic and transient phases with batonnents.
