Densities and Excess Molar Volumes of the Ternary Mixture 2-Butanol + Chloroform + Benzene and Binary Mixtures 2-Butanol + Chloroform, or + Benzene over the Temperature Range (288.15 to 313.15) K

Abstract

Densities and Excess Molar Volumes of the Ternary Mixture 2-Butanol + Chloroform + Benzene and Binary Mixtures 2-Butanol + Chloroform, or + Benzene over the Temperature Range (288.15 to 313.15) K Densities F 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 F 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 Nagata-Tamura equation for ternary mixtures.

Volumetric and Viscometric Behavior of Binary Systems 2-Butanol + PEG 200, + PEG 400, + Tetraethylene Glycol Dimethyl Ether, and + N-Methyl-2-pyrrolidone

“…Since the conditions exist both for dipole–dipole interactions and hydrogen bonds among the unlike molecules which would lead to negative excess molar volumes, the predominant effect of volume expansion could be the consequence of breaking or stretching of hydrogen bonds between the alcohol molecules and steric hindrance induced by branching. The fact that the branched structure of 2-butanol is unsuitable for effective packing is confirmed by our ongoing investigations on 1-butanol + TEGDME binary system but also by our previous works involving mixtures of 1-butanol or 2-butanol with chloroform. , …”

However, at lower temperatures and over 0.4 alcohol mole .…”
