Lyotropic nematogenic system potassium laurate-1-decanol-water: Method of synthesis and study of phase diagrams

The results of the study of the potassium laurate-1-decanol-water lyotropic composition are presented. The procedure of preparation of micellar solutions provides the good reproducibility of the phase diagrams. The configurations of the domains of the liquid crystal order are constructed on the concentration plane at the constant temperature as well as the temperature sections (T, C 1-decanol) (at the constant ratio of potassium laurate to water) and (T, C water) (at the constant ratio of potassium laurate to 1-decanol). The liquid-crystal phases observed are described.
