摘要:

The partial structure factors of molten copper haildes (CuCl, CuBr and CuI) have been derived from the observed total structure factors by means of the Reverse Monte Carlo simulation technique. The static dielectric functions are also obtained using these partial structure factors and it is found that these experimental dielectric functions satisfy either the inequality form ϵ(q)ϵ1 or ϵ(q) < 0.

摘要:

A simple formalism is provided to relate the viscosity and the chemical diffusion coefficient of binary liquid alloys. Only under simplified considerations, it reduces to the form of Stokes-Einstein relation. The positive and negative deviations of the viscosity from the additive rule of mixing have been ascribed to the role of energetic and size effects.

摘要:

Excess free energy of mixing ΔFtotalΔFABin the binary mixtures of long chain alchols and amines in nonpolor solvent carbon tetrachloride have been calculated with the help of our proposed equation. The novelty of our equation is that it involves separate estimation of excess free energy of mixing due to interaction between polar-polar molecules, polar-induced nonpolar molecules and induced nonpolar molecules and a picture of molecular interaction in these mixtures has been elicited with the help of these parameters.

摘要:

Vapor-liquid equilibrium at 94 kPa has been determined for the ternary system methyl 1,1-dimethylethyl ether (MTBE) + oxolane + heptane. The system deviates positively from ideality and no azeotrope is present. The ternary activity coefficients and the boiling points of the system have been correlated with the composition using the Redlich-Kister, Wilson, NRTL, UNIQUAC, UNIFAC, and Wisniak-Tamir relations. Most of the models allow a good prediction of the activity coefficients of the ternary system from those of the pertinent binary systems.

摘要:

Excess molar volumes,VEhave been claculated from the density data of aqueous solutions of 1-propanol, 2-propanol, allyl alcohol and propargyl alcohol at temperatures ranging from 30°-50°C. TheVEvalues have been found to be negative at all temperatures. The volume contraction for saturated alcohols, both straight and branched chain, in aqueous media is accounted for mainly by the hydrophobic effect, while that for unsaturated alcohols is explained primarily by the formation of H-bond between the alcohol and water. ThedVE/dTvalues have been found to be positive for all alcohols. The temperature dependence ofVEis thought to be strongly influenced by the structural properties of water.
