Abstract
The dynamic viscosity η of the binary mixture 1-methylnaphthalene+2,2,4,4,6,8,8-heptamethylnonane was measured in the temperature range 293.15 to 353.15 K (in progressive 10 K steps) at pressures of 0.1, 20, 40, 60, 80, and 100 MPa. The composition of the system is described by nine molar fractions (0 to 1 in 0.125 progressive steps). The density ρ was measured at pressures from 0.1 to 60 MPa in progressive 5 MPa steps. The measurements of η are used to determine the excess viscosity η E and the excess activation energy of flow ΔG E as a function of pressure, temperature, and composition. Some models have been used to represent the viscosity of this binary mixture.
