Density and Viscosity Measurements of Binary Alkanol Mixtures from (293.15 to 333.15) K at Atmospheric Pressure

Abstract

Density and viscosity of binary mixtures of {x1isobutanol + x21-propanol}, {x1isobutanol + x22-propanol}, and {x13-amino-1-propanol + x21-propanol} were measured over the entire composition range and from temperatures (293.15 to 333.15) K at ambient pressure. The excess molar volumes and viscosity deviations were calculated and correlated by the Redlich–Kister and McAllister equations, respectively. The excess molar volumes are negative over the entire mole fraction range for all of the mixtures and become more negative with increasing temperature. The viscosity deviations of the binary mixtures are negative in the entire composition range and decrease with increasing temperature.
