Excess Volumes of Binary Mixtures of Alcohols in Methylcyclohexane

Abstract
Excess volumes of binary mixtures of alcohols in methylcyclohexane have been determined at 30.0 and 40.0 °C, using a modified dilatometer of Brown and Smith. The systems include: (I) 1-propanol – methylcyclohexane, (2) 1-butanol – methylcyclohexane, (3) 1-pentanol–methylcyclohexane, and (4) 1-hexanol–methylcyclohexane. The VE values are found to be positive over the entire range of composition in all the four systems and the values are interpreted on the basis of the structure-breaking effect of methylcyclohexane.
