An Experimental Study of the Viscometric and Volumetric Properties of 1-Alkanol (C3 – C11) Ternary Systems at Different Temperature Levels.

Abstract

Kinematic viscosity-composition and density-composition data of ten ternary systems containing 1-propanol, 1-pentanol, 1-heptanol, 1-nonanol,
and 1-undecanol have been experimentally measured and reported in this study. Seven intermediate composition points and pure components
densities and kinematic viscosities were measured at 293.15 and 298.15 K temperature levels. The measured values of kinematic viscosity
were compared to viscosity values predicted by various viscosity models. The investigated models are: the generalized McAllister three-body
interaction model, the GC-UNIMOD model, the generalized corresponding states principle (GCSP) model, and the Allan and Teja correlation.
The analysis of the models testing results shows that the generalized McAllister three-body interaction model gave the best prediction results.
