Density, Speed of Sound, and Viscosity for Binary Liquid Mixtures of 2-(2-Ethoxyethoxy)ethanol with Methyl Acrylate, Ethyl Acrylate, or Butyl Acrylate from T = 288.15 to 318.15 K and P = 101 kPa

Abstract

In this study, the density (ρ), speed of sound (u), and viscosity (η) of the binary liquid mixtures of an industrially important solvent 2-(2-ethoxyethoxy)­ethanol (carbitol) with acrylic esters [methyl acrylate, ethyl acrylate, and butyl acrylate (BA)] have been measured over the entire composition range at temperatures from T = 288.15 to 318.15 K and at atmospheric pressure P = 101 kPa. The excess molar volume (V m E), excess isentropic compressibility (κ s E), and viscosity deviations (Δη) have been calculated from the related experimental data. All excess properties are negative at all temperatures for all the mixtures, suggesting the compactness of binary mixture except the positive V m E values for some concentrations of BA mixtures. Deviation from ideality increases with rising temperature for both excess molar volume and excess isentropic compressibility but a decrease in deviation from ideality with temperature rise has been observed for viscosity deviations. Finally, excess properties have been fitted to the Redlich–Kister polynomial.

Apparent Molar Properties and Viscosity Studies of Ternary Systems Composed of Model Lignin and Xylose in DBU Based Ionic Liquid–DMSO Solutions

“…The volumetric, acoustic, and the viscosity data of the solutions help to explain the mode of interactions along with the strength of the interactions arising from various components present in the liquid mixture. 54 The density of both ternary systems, I-D-L and I-D-X, decreases with rising temperature and increases with an increase in the concentration of the solute, model lignin, and model xylose (Figures S3 and S4). Prior to the ternary system studies, the binary solutions of [DBU][OTf] and DMSO (0.1− 0.4 m) were prepared, and the density and speed of sound were investigated as it is important to know about the solvent of the ternary system.…”

Speed of Sound and Excess Properties of (Ethanol + Isooctane) Binary System

“…Thermodynamic and acoustic properties can be used to develop molecular models for describing the behavior of liquid–liquid binary systems and explore the arrangement of different components in the liquid mixture. − Many thermodynamic properties can be derived from the speed of sound, and the speed of sound is also important in the design of fuel injection. On the basis of the Rayleigh–Brillouin scattering principle, , our research group built a sonic measurement system which can be used for high temperature measurement and can determine the speed of sound in various liquids. − In previous studies there is little research on the thermodynamic properties of the binary system of ethanol (1) + isooctane (2) at high temperatures.…”
