The densities of binary mixtures of n-hexadecane and cyclohexane at high pressures were measured in the range of (6.895 to 62.053) MPa at six different temperatures varying from (318.15 to 413.15) K and for eight compositions. The measurements were made by a high-pressure Anton Paar DMA 512 P densimeter integrated with the Ruska 2370 mercury Free PVT System. The densimeter was calibrated using analytical grade toluene, cyclohexane, and n-heptane as calibration fluids. The experimental error of density measurements is estimated as 0.5 kg*m-3. The measured densities at 348.15 K agree well with the available literature values at different pressures. The excess volumes, thermal expansion, and isothermal compressibility coefficients were obtained from measured densities. All data were correlated successfully with a modified Peng-Robinson equation of state.
