In the benzene solutions the association, if any, is much weaker probably due to competitive interactions between the solute and the solvent. The conformational equilibrium in 1,3-dimethoxybenzene (1,3-DMB) and its benzene solutions was studied using the non-linear dielectric effect (NDE) method.

The excess molar volumes VmE, relative permittivity increments δϵr, and excess molar polarization PmEof { x CH2CCH3CO2CH3+ (1 − x) ( C6H6, or C7H8, or o -C8H10, or m -C8H10, or p - C8H10, or C8H10, or c -C6H12)} have been measured at the temperatures 298.15 K and 308.15 K. The results for VmE, δϵr, and PmEindicate that structure-disruptive interactions between the acrylic ester and hydrocarbons predominate over the specific interactions and contribute to the sign and magnitude of the individual excess functions.

Preliminary measurements of the dielectric constant of toluene and benzene have been performed along the saturation line, up to 100°C. Ultrasonic velocities, u, and isentropic compressibilities, κs, have been measured for binary mixtures of quinoline (C9H7N) with carbon tetrachloride (CCl4), benzene (C6H6) and chloroform (CHCl3) at 303.15 and 313.15 K, for mixtures of C9H7N with methylene chloride (CH2Cl2) at 293.15 and 303.15 K, and for mixtures of C9H7N with cyclohexane (c-C6H12) at 303.15 K. Measurements of relative permittivities, ε, and refractive indices, n, have also been made for binary mixtures of C9H7N with CCl4, CHCl3, CH2Cl2, C6H6 and c-C6H12 at 303.15 K. The quantities Δκs and Δε which refer, respectively, to the deviations of the isentropic compressibilities and relative permittivities of the mixtures from the values arising from the mole-fraction mixture law, have been calculated. heavy 3.2 Dibenzyl (60°C) 2.5 Benzil (80°C) 10 Diesel Fuel 2.1 Benzine 2 Diethyl carbonate 2.8 Benzyl alcohol 13.5 Diethylamine 3.8 Benzyl chloride 7 Dimethylether (methyl ether) 5 Benzyl amine 4.6 Diofan 32 The mixture viscosities have been correlated with semi empirical equations. For C9H7N–c-C6H12, Δε is very slightly negative at low mole fractions of C9H7N and very slightly positive for high mole fractions. The results were summarized using a single polynomial in T, except for the perfluoroalkanes near the critical points.

The equilibrium constants Kf for the formation of a 1 : 1 complex of C9H7N with CHCl3 and CH2Cl2, as calculated from the relative permittivity data, are in accord with the theory of Barriol and Weisbecker, which is based upon the electrostatic interactions of the solute with the liquid. f dielectric constant benzyl chloride 68 6.4 benzyl cyanide 68 18.3 benzyl cyanide 155 6 benzyl salicylate 68 4.1 benzylamine 68 4.6 benzylethylamine 68 4.3 benzylmethylamine 67 4.4 beryl 6 biphenyl 20 biwax 2.5 bleaching powder 4.5 bone black 5.0-6.0 bornyl acetate 70 4.6 boron bromide 32 2.6 The molecular orbital PM3 method has been applied to calculate the dipole moments and energy of molecular clusters. At 25°C the values for benzene's dielectric constant were 2.2747±0.0003, but the higher limit is presently preferred.

Landolt-Börnstein Group IV `Physical Chemistry'. Densities, refractive indices, absolute viscosities, and static dielectric constants have been measured over the entire range of composition for binary mixtures of 2-methylpropan-2-ol with hexane, benzene, propan-2-ol, methanol, ethanol, and water at 303.2 K. Excess molar volumes were fitted to Redlich-Kister equations. The compositional variation of excess and deviation functions has been expressed in terms of the Redlich−Kister equation. The value of the dielectric constant of pure benzene is important as a standard value. Δκs is negative throughout the whole range of composition in each case.

The reasons for the discrepancies appear explicable in view … ResearchGate has not been able to resolve any citations for this publication. We report our experimental observations of the variation of Kerr constant in five binary liquid mixtures of acetonitrile in benzene, toluene, nitrobenzene, chlorobenzene and o-nitrotoluene with different molar fractions.

From the values of ε and nD of the lactone + benzene mixtures, the Kirkwood correlation factor, g, was calculated indicative of the structures of the mixtures.

The above functions of ternary systems were also calculated using the data of constituent binary pairs and employing Redlich−Kister, Tsao and Smith, and Kohler equations. Preliminary measurements of the dielectric constant of toluene and benzene have been performed along the saturation line, up to 100°C. The excess volumes and relative permittivity deviation are calculated from the density and relative permittivity data. This document is part of Volume 17 `Static Dielectric Constants of Pure Liquids and Binary Liquid Mixtures (Supplement to IV/6)' of Landolt-Börnstein Group IV `Physical Chemistry'. The nonlinear dielectric effect (NDE) has been applied to study the molecular association in tetrahydrofuran (THF) solutions in benzene and in cyclohexane. For the pure lactones the dipole moments, μ, the molar polarizability, PM, and the molar refractivity, RM, were determined. The apparent dipole moments, µapp, of C9H7N in CCl4 and C6H6 have been calculated. The Kirkwood correlation parameter, g, as calculated from the data on ε and n, for C9H7N–CHCl3 and C9H7N–CH2Cl2 was used to obtain Δg, which refers to the deviation of the Kirkwood correlation parameter of the mixture from the values arising from the mole-fraction mixture law. These results fall within the range of the best recent values obtained in other laboratories.
