TL;DR: The liquid crystalline phases formed in the concentration range between the hexagonal and the lamellar phase in the binary system C 16 TACl-H 2 O have been studied by 2 H, 14 N, and 35 Cl NMR, low-angle X-ray diffraction and optical microscopy as discussed by the authors.
Abstract: The liquid crystalline phases formed in the concentration range between the hexagonal and the lamellar phase in the binary system C 16 TACl-H 2 O have been studied by 2 H, 14 N, and 35 Cl NMR, low-angle X-ray diffraction and optical microscopy. A cubic phase and three anisotropic so-called intermediate phases have been found. At 45 o C the hexagonal phase is stable up to 75 wt % C 16 TACl. Between 75% and 79%, a biaxial phase (Int-1) built up by long rods with noncircular cross sections is formed

TL;DR: In this article, the Redlich−Kister type polynomial equation of the third degree was used to derive the binary coefficients of a mixture of dimethyl carbonate with methanol, chloroform, carbon tetrachloride, cyclohexane, and dichloromethane.
Abstract: Experimental values of density, viscosity, and refractive index at (298.15, 303.15, and 308.15) K and the speed of sound data at 298.15 K for the binary mixtures of dimethyl carbonate with methanol, chloroform, carbon tetrachloride, cyclohexane, and dichloromethane are presented over the whole range of mixture composition. From these data, excess molar volume, deviations in viscosity, speed of sound, isentropic compressibility, and Lorenz−Lorentz molar refractivity have been calculated. These results are fit to the Redlich−Kister type polynomial equation of the third degree to derive the binary coefficients. The standard error values are estimated between the calculated and experimental data points.

TL;DR: In this paper, the solubility behaviors of binary HFC-125 (CF3−CF2H), HFE-143a (CF 3−CH3), and HFE -125 + [emim][Tf2N] systems with room-temperature ionic liquid 1-ethyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide ([emim]Tf 2N]) have been studied using a gravimetric microbalance method from (283 to 348) K and
Abstract: Solubility behaviors of binary HFC-125 (CF3−CF2H), HFE-125 (CF3−O−CF2H), HFC-143a (CF3−CH3), and HFE-143a (CF3−O−CH3) systems with room-temperature ionic liquid 1-ethyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide ([emim][Tf2N]) have been studied using a gravimetric microbalance method from (283 to 348) K and/or volumetric and cloud-point methods. Vapor–liquid equilibrium (VLE) data for HFC-125 + [emim][Tf2N] and HFE-125 + [emim][Tf2N] systems have been well correlated with our equation-of-state (EOS) model, which predicted vapor–liquid–liquid equilibria (VLLE) for both of these binary systems, and the VLLE have been experimentally proved. As for the binary systems of HFC-143a + [emim][Tf2N] and HFE-143a + [emim][Tf2N], only VLLE experiments have been made, and partial miscibility (temperature and composition: VLLE−Tx) data are well correlated with the NRTL (nonrandom two-liquids) activity model. While the immiscibility gap of the HFC-125 binary system is smaller than that of the HFE-125 system, ...
