ABSTRACT
The densities and kinematic viscosities of 10 binary subsystems of the regular quinary system, benzene (1) + toluene (2) + ethylbenzene (3) + heptane (4) + cyclooctane (5), were measured at 308.15 K and 313.15 K over the entire composition range. The viscosity-composition data reported herein were utilized to examine the predictive capability of some viscosity models, namely, the predictive version of the McAllister model, a group contribution method (GC-UNIMOD), a generalized corresponding states principle (GCSP), and the Allan and Teja correlation. The results of testing showed that the McAllister model outperformed all other models except for systems containing cyclooctane. The results also showed an overall average absolute deviation (%AAD) of 1.25% for systems that did not contain cyclooctane.
