  • Excess molar volumes of binary mixtures (an ionic liquid + water): A . . .
    Volumetric properties of binary mixtures (density, excess and partial molar volumes) are complex properties because they depend not only on size, shape, and chemical nature of the components of a mixture [13], [14], but also on the (solute + solute, solvent + solvent, solute + solvent) interactions, and on structural effects arising from interstitial accommodation due to differences in molar
  • Density, Refractive Index and Excess Molar Volume of Binary Liquid . . .
    In continuation of our studies on thermodynamic, acoustic and transport properties of some binary mixtures of ethyl acetate with 1-alkanols [1-2] the present paper reports the excess molar volume ( ) and excess molar refraction ( ) for binary solvent mixtures containing ethyl acetate, 1-methanol, 1-ethanol, 1-propanol, 1-butanol, 1-hexanol, 1- octanol over the entire mole fraction range at 303
  • Densities and excess molar volumes of the binary systems of the ionic . . .
    Both binary systems were studied in the whole composition range along with the pure compounds Excess molar volumes were calculated from the experimental densities and were fitted with the Redlich–Kister polynomial equation Excess molar volumes were negative for the mixtures and became more negative as the temperature increased
  • Densities, Volumes, Excess Volumes - DDBST GmbH
    VE - Excess Volumes, Mixture Densities The data bank DDB-VE contains a large amount of mixture densities and excess volumes Excess volumes represent the deviation from ideal mixing volume and are crucial for describing the effect of pressure on the real behavior (activity coefficients and fugacity coefficients)
  • Densities, Excess Molar Volumes and Excess Refractive . . . - Springer
    In this study, density, excess molar volume, refractive indices and related properties are reported for D 2 O–H 2 O binary solutions Graphical Abstract Similar content being viewed by others Chapter Article
  • Thermodynamic and acoustic properties of binary mixtures: A . . .
    Renewable and Particularly emphasizing excess molar volume (VE), excess molar enthalpy (HE), and speed of sound, this review has highlighted the complex dependency of thermodynamic and acoustic parameters on molecular interactions and temperature in binary mixtures
  • Volumetric Properties of Binary Mixtures Containing Ionic Liquids and . . .
    On the basis of the experimental densities, excess molar volumes were calculated Comparison of excess molar volumes of six binary systems reveals the slight influence of the IL’s cation on these physical properties and the small temperature dependence of VE for systems containing dimethyl sulfoxide
  • Density, Viscosity, and Excess Molar Volume of the Binary Mixtures of 1 . . .
    ABSTRACT: Experimental data on the density and dynamic viscosity of binary mixtures of 1-propanol, 1,2-propanediol, 1,3-propanediol, and glycerol at temperatures from 293 15 to 343 15 K are reported For the majority of binary mixtures, this is the first time that the dynamic viscosity has been measured Excess molar volumes are calculated and fitted to Redlich−Kister polynomials The
  • DENSITIES AND EXCESS MOLAR VOLUMES FOR BINARY SOLUTION OF WATER . . .
    Among the various thermodynamic properties, the excess molar volume, VE, has been of much interest for the practical purpose of determining composition from the density measurement (Rathnam et al , 2008; Redlich and Kister, 1948) Density and excess molar volume are significant for the design of new processes and the study of molecular interactions in binary liquid systems (Chen and Knapp
  • 1. 22. 11: Volumes: Liquid Mixtures: Binary: Method of Tangents
    The volumetric properties of a binary liquid (homogeneous) mixture is summarized by a plot of excess molar volume V m E against, for example, mole fraction x 1 In fact this type of plot is used for many excess molar properties including G m E and H m E Here we consider a general excess molar property X m E
  • Excess Volumes of Liquid Nonelectrolyte Mixtures | Volume Properties . . .
    In the section on experimental results, the discussion of excess molar volumes focuses on binary systems belonging to one of the following three groups: (I) mixtures of organic, aprotic liquids, (II) mixtures containing alcohols or alkanoic acids, and (III) aqueous solutions of nonelectrolytes
