Measurement of the vapor pressure of methanol-n-decanol and ethanol-n-decanol mixtures

Abstract

Molar excess Gibbs free energies of mixtures of methanol and ethanol with n-decanol were obtained from static vapor pressure measurements over the temperature range 20–50 °C. The molar excess entropies of the system methanol–decanol are predominantly negative at 25 °C; those of ethanol–decanol are positive.
