Volumetric Behaviour of an Isomeric and Branched Alcohols with 1,2-Dichloroethane

Abstract

Excess volumes (V^E ) for the binary mixtures of 1,2-Dichloroethane with i-propanol, i-butanol, secbutanol, tert-butanol, i-pentanol, i-hexanol and cyclohexanol have been determined at 303.15 K, by dilatometric method over the entire range of composition. Values of V^E are positive over the whole mole fraction range studied. Results are explained in terms of break up of hydrogen bonds, interstitial accommodation of 1,2-dichloroethane in alcohol aggregates and possible hydrogen bond interaction of the type Cl … H[sbnd]O between unlike molecules.

Key Words:

• Hydrogen bonds
• excess volumes
