Volumetric behaviour of binary systems of cyclohexane with the hexanol isomers at 298.15 K

Abstract

Excess molar volumes, vE, based on density measurements taken at 298.15 K, were calculated for ten binary mixtures consisting of cyclohexane and the following isomers of hexanol: 3,3-dimethylbutan-1-ol, 2,2-dimethylbutan-1-ol, 2,3-dimethylbutan-1-ol, 2-ethylbutan-1-ol, 3-methylpentan-1-ol, 4-methylpentan-1-ol, 3,3-dimethylbutan-1-ol, 2-methylpentan-3-ol, hexan-3-ol and 2,3-dimethylbutan-2-ol. The vE values were positive over the entire range of concentration, except in the case of the binary system of x1 cyclohexane + x2 3-methylpentan-1-ol, for which the vE values were negative for x1 < 0.1. A discussion of the behaviour of these mixtures, based on the experimental results, is included. © 1991.
