ABSTRACT
The aim of this work is to report the (p, ?, T) properties for the carbon dioxide (x) + heptane (1 x) and carbon dioxide (x) + tridecane (1 x) from 313 K to 363 K. Experimental densities were obtained by measuring the vibrating period of each mixture in a commercial vibrating tube densimeter. Binary mixtures were initially synthesized at compositions of x = (0.0218, 0.3148, 0.5085, 0.7514, 0.9496) and x = (0.0955, 0.2526, 0.5259, 0.7549, 0.8978) for mixtures containing heptane and tridecane, respectively. Excess molar volumes are negative for the whole range of compositions. Experimental densities are well represented (within experimental uncertainty) through the Benedict-Webb-Rubin-Starling equation of state, and both 5-, and 6-parameters correlations. Derived thermodynamic properties were computed using the 5-parameter equation.
