    • Abstract


      Volume changes on mixing of isomeric butanols withn-heptane have been determined at 25°C and that of tertbutanol at 26°C. All the four systems show a positive excess volume throughout concentration range. The excess volumes have been found to vary in the order of tert >sec >iso >n-butanols. The order of the excess volume has been attributed to breaking of hydrogen bonds of associated species of alcohol by dilution withn-heptane and more random distribution ofn-heptane molecules.
