The enthalpies of solution of Hexa-1-ol and Heptan-1-ol in water

Abstract

The solubility of hexan-1-ol and heptan-1-ol in water has been measured over the temperature range 278-308 K. The free energy, enthalpy and heat capacity of solution of these alcohols has been calculated from this data and the enthalpy and heat capacity have also been obtained by direct calorimetric measurement. The thermodynamic function changes on solution of these two alcohols follow the pattern of the lower members of the homologous series. The results have been compared qualitatively with data for the other alcohols and for the hydrocarbons.
