In this work, the physical properties of binary mixtures of n-hexadecane with toluene or ethylbenzene were measured. Density and viscosity were measured at temperatures ranging from (293.15 to 373.15) K, and the speed of sound was measured at temperatures ranging from (293.15 to 333.15) K. Density mole fraction and temperature data were fit to a fourth-order polynomial. Viscosity mole fraction data were fit using the three-body McAllister model, while the viscosity deviations were fit to a Redlich鈥揔ister type equation. For both two-component mixtures, the speed of sound at 293.15 K decreased as the mole fraction of the aromatic compound increased until a minimum was reached after which the speed of sound increased slightly to the value of the pure aromatic compound. The bulk modulus was calculated from density and speed of sound data. For both 2-component mixtures, the bulk modulus at 293.15 K decreased slightly as the mole fraction of the aromatic compound increased until a minimum was reached after which the bulk modulus increased to its highest value, which is the value for the aromatic compound. Flash points for the mixtures ranged from (278.5 to 408) K, and surface tension values ranged from (27.3 to 29.2) mN路m^鈥?.
