The densities and excess molar volumes V-m(E) for binary liquid Mixtures of (1,2-propanediol carbonate + benzene. or toluene, or ethylbenzene, or styrene) have been measured as a function of compositions using a vibrating-tube densimeter in the temperature range of (293.15 to 353.15) K and at atmospheric pressure. The V-m(E) results were correlated using the fourth-order Redlich-Kister equation. It was found that the V-m(E) in these systems studied increases with rising temperature.
