Thermodynamics of Mixtures Containing Alkoxyethanols. XXIV. Densities, Excess Molar Volumes, and Speeds of Sound at (293.15, 298.15, and 303.15) K and Isothermal Compressibilities at 298.15 K for 2-(2-Alkoxyethoxy)ethanol + 1-Butanol Systems

Abstract

Densities, ρ, and speeds of sound, u, of systems formed by 2-(2-methoxyethoxy)ethanol (22MEE), 2-(2-ethoxyethoxy)ethanol (22EEE), or 2-(2-butoxyethoxy)ethanol (22BEE) and 1-butanol (1-BuOH) have been measured at (293.15, 298.15, and 303.15) K and atmospheric pressure using a vibrating-tube densimeter and sound analyzer (Anton Paar model DSA-5000). The ρ and u values were used to calculate excess molar volumes, VE , at the mentioned temperatures and deviations from the ideal behavior at 298.15 K of the thermal expansion coefficient, ΔαP, and of the isentropic and isothermal compressibilities, ΔκS and ΔκT, respectively.
