Measurements of the viscosity and density of three hydrocarbons and the three associated binary mixtures versus pressure and temperature

The dynamic viscosity ;/ and density p of three pure substances (heptane, methylcyclohcxane, l-methylnaphthalenel and of the three associated binary nlixtures {heptane + methylcyclohexane, heptane + I-methyh~aphthalene, methylcyclohexane+ l-methyhmphthalene) were measured as a function of temperature T [303.15, 323.15, and 343.15 K) and pressure P I~< 100 MPaL For the binary mixtmes the mole fraction .v of each component was successively 0, 0.125, 0.25. 0.375, 0.5, 0.625. 0.75, 0.875, and I. The total experimental results represent 432 different points: 54 Ibr the pure substances and 378 for the binary mixtures Ix ~0 and II.
