Abstract

This paper reports on equipment for the automatic measurement of the density of binary mixtures as a function of concentration. The equipment is applied to mixtures of 1-propanol and water at 5, 15, and 25°C. An equilibrium mixture model, in which an alcohol-water solution is regarded as an ideal associated mixture, is fitted to the experimental data. Thermodynamic parameters characterizing the association of water to nonpolar alkyl groups (hydrophobic solvation) and to polar hydroxyl groups (hydrophilic solvation) are estimated.
