    • Abstract

       

      A simple dewar type calorimeter has been constructed to determine the enthalpy of mixing in dilute concentration range and its performance checked by determining the heats of mixing of cyclohexane (l)-n-hexane (2) and ethanol (1)n-hexane (2) systems. The heats of mixing ofn-butylamine withn-hexane and ethanol have been determined at 30° C. The enthalpy of ethanol-butylamine complex calculated by a thermochemical cycle was found to be-40.3 kJ/mol.
