Thermodynamic functions for the system ethanol + cyclohexane from vapour pressures and enthalpies of mixing

Abstract

Activity coefficients for the system ethanol + cyclohexane at 45°C are obtained from vapour pressure measurements using a stepwise dilution apparatus. Enthalpies of mixing for the range xA= 0.1 to 0.99 (xa= mole fraction of ethanol) supplementing those reported previously for the range up to xA= 0.16, are obtained at seven temperatures by isothermal dilution calorimetry. Conversion of the activity coefficients to 6.7°C shows that the activity data obtained previously from freezing-point measurements were in error, owing to suspected solid solution formation.
