Densities and excess molar volumes of the ternary mixture 2-butanol plus chloroform plus benzene and binary mixtures 2-butanol plus chloroform, or plus benzene over the temperature range (288.15 to 313.15) K

Abstract

Densities rho and excess molar volumes V(E) of the 2-butanol + chloroform + benzene ternary mixtures and two binaries, 2-butanol + chloroform and 2-butanol + benzene, have been determined. Experimental rho measurements have been performed at six temperatures, (288.15, 293.15, 298.15, 303.15, 308.15, and 313.15) K, and atmospheric pressure with an Anton Paar DNA 5000 digital vibrating tube densimeter. Excess molar volumes V(E) were correlated by the Redlich-Kister equation for binary mixtures and the Naoata-Tamura equation for ternary mixtures.
