Measurements and Modeling of Physicochemical Properties of Pure and Binary Mixtures Containing 1,2-Dimethoxyethane and Some Alcohols

Abstract

In this paper, experimental values of densities, speeds of sound, and refractive indices in a temperature range of 293.15−323.15 K have been measured as a function of composition for the binary liquid mixtures of 1,2dimethoxyethane with alcohols such as methanol, propan-1-ol, propan-2-ol, and butan-2-ol. From these experimental values, excess/derived properties such as excess molar volume, isentropic compressibility, deviation in isentropic compressibility, and deviation in the refractive index have been calculated. Excess/derived properties have been correlated using the Redlich− Kister equation and physicochemical properties modeled using the cubic plus association equation of state for pure and binary mixtures. The results are interpreted with respect to possible molecular interactions between components.

Intermolecular Interactions of Binary Mixtures Comprising 2‐Benzylaminoethanol with Alcohols (C1−C3) at Different Temperatures: Experiments and Modelling

“…where the density is obtained from PC‐SAFT EoS, and $${{z}_{i}}$$ is the weight fractions of component $${i}$$ in the mixture. Good results were obtained in our previous studies [33,36,37] …”

Study of Nonideality Behavior of p-Methylacetophenone and 1-Alkanol Mixtures from Measurement and Modeling of Density and Viscosity

“…According to Table S3, we can conclude that low statistical deviations are obtained when three parameters are used in the modeling of excess molar volume and deviation in viscosity, showing the correct modeling of the experimental data of V E and Δη using the Redlich–Kister polynomial. From Table S3, we can see that the excess molar volumes values are negative; these values imply that the attractive forces of the p -methyl acetophenone + alcohol are strong, e.g., induced dipole–dipole forces between p -methyl acetophenone and alcohol ,, and the contraction effect that occurs in the mixtures, i.e., the volume of the mixture is less than the sum of the volumes of the pure liquids.…”
