Phase diagram of the liquid crystal system of water-decanol-lanthanum nitrate-decaethylene glycol monododecyl ether

Russian Journal of Physical Chemistry (impact factor: 0.46). 04/2012; 84(5):802-807. DOI:10.1134/S003602441005016X pp.802-807

ABSTRACT The phase behavior of a self-organizing system based on the nonionic surfactant of decaethylene glycol monodecyl ether-lanthanum
nitrate hexahydrate-water and decanol is presented. A system phase diagram was constructed. The concentration, temperature
ranges of existence and types of liquid crystal phases were established. Analysis of structural changes during the phase transitions
hexagonal phase-lamellar phase-isotropic liquid was made on the basis of data obtained by viscosimetry and self-diffusion
NMR.
