The dynamic viscosityη and densityρ of 10 pure substances and three binary systems were measured as a function of temperatureT (298.15, 313.15, 333.15, 353.15, and 363.15 K.) and pressureP (⩽100 MPa). The pure substances were toluene,p-xylene,m-xylene,o-xylene, methylcyclohexane, methylnaphthalene, decahydronaphthalene, phenyldodecane, heptamethylnonane, and tetramethylpentadecane (pristane). The three binaries were toluene + tetramethylpentadecane, toluene + methylnaphthalene, and toluene + heptamethylnonane, for molar fractionsx of toluene ranging between 0 and 1. The three binaries are highly “contrasted” systems, i.e., systems in which the viscosities of the pure components are very different for eachP, T pair. In all, 547 experimental determinations were carried out (279 experimental data for viscosity of the pure substances and 268 data concerning the mixtures: x⊋0 and 1).
