Abstract

Densities and viscosities of short chain (C1-C3) n-alcohol-water mixtures have been measured in the entire range of composition at temperature ranges (350.7 to 476.2. K) and at pressures up to 40. MPa. The Eyring theory for viscosity incorporated with the Patel-Teja (PT) equation of state was applied to the correlation of experimental viscosities, when Redlich-Kister (RK) or van der Waals one fluid (vdW1) mixing rules were applied to mixtures. The two binary interaction parameters of these mixing rules were determined by fitting of viscosity data. Moreover, the density values were also evaluated using the parameters which were determined in viscosity correlation. The Eyring + PT + RK model gave better correlation of viscosities for alcohol-water mixtures within a deviation of 1.5% (3.9% for the Eyring + PT + vdW1 model). The Eyring + PT + RK model was found to be also superior in terms of density evaluation so as to be the deviation within 4.8% (18.7% for the Eyring + PT + vdW1 model).
