ABSTRACT

This paper presents densities and viscosities of binary mixtures of ethanol with 1-propanol, 1-butanol, and 1-pentanol from (293.15 to 328.15) K at 0.1 MPa over the entire composition range. Densities come from a vibrating tube densimeter while viscosities are from a pellet microviscometer. A three-body McAllister equation correlates the kinematic viscosities. The excess molar volumes and viscosity deviations calculated from the experimental data both have negative deviations from ideality over the temperature range. A prediction with a generalized, three-body McAllister equation and a generalized corresponding states principle (GCSP) equation indicates that the generalized McAllister equation is a better predictor having results within 3 % of the observed kinematic viscosities.
