Volumetric, Viscometric, Ultrasonic, and Refractive Index Properties of Liquid Mixtures of Benzene with Industrially Important Monomers at Different Temperatures (original) (raw)

2009, International Journal of Thermophysics

The densities, ρ, viscosities, η, ultrasonic speeds, u, and refractive indices, n D , of pure benzene, methyl acrylate (MA), ethyl acrylate (EA), butyl acrylate (BA), styrene (STY), and their binary liquid mixtures have been measured over the entire composition range at 298.15 K, 303.15 K, 308.15 K, and 313.15 K. The experimental data have been used to calculate excess molar volumes. Partial molar volumes of MA/EA/BA/STY in benzene at infinite dilution and at different temperatures have also been evaluated. The results were discussed in terms of molecular interactions prevailing in the mixtures. Keywords Alkyl acrylates • Benzene • Binary mixtures • Excess functions • Molecular interactions 1 Introduction This study is a continuation of our earlier studies [1-5] on molecular interactions of binary non-aqueous liquid mixtures using thermodynamic and transport properties. Here we extend our study to the binary mixtures containing commercially important monomers, methyl acrylate (MA), ethyl acrylate (EA), butyl acrylate (BA), and styrene (STY) with benzene. A knowledge of thermodynamic and transport properties of these industrially important solutions is often required for industrial applications
