Excess molar volumes of benzene with certain isomers of hexanol

Abstract

Excess volumes of binary mixtures of several hexanol isomers with benzene were calculated from their density measurements at 298.15 K. The following isomers were used: 3-methylpentan-1-ol, 4-methylpentan-1-ol, 2-ethylbutan-1-ol, 2,2-dimethylbutan-1-ol, 2,3-di-methylbutan-1-ol, 3,3-dimethylbutan-1-ol, hexan-3-ol, 3,3-dimethylbutan-2-ol and 2,3-di-methylbutan-2-ol. For all mixtures the vE values are positive over the entire range of composition and the curves show an asymmetrical form whose interpretation is discussed. © 1992.
