ABSTRACT
Compressed liquid densities of n-decane + n-dodecane binary mixtures were measured with a vibrating-tube densimeter at temperatures from (283 to 363) K and pressures from (0.1 to 100) MPa over the whole range of composition. The binary mixtures n-decane (1) + n-dodecane (2) were prepared at mole fractions of (x1 = 0, 0.2297, 0.4436, 0.6433 0.7841, and 1.0), respectively. The experimental densities of binary mixtures were successfully correlated with the Tait-type equation, and the absolute average percentage deviations of the experimental and calculated values were 0.048%, 0.055%, 0.059%, 0.058%, 0.068%, and 0.052%, respectively. In addition, the excess molar volume was calculated for whole range of temperature, pressure and composition.
