Excess volumes and partial molar volumes of binary mixtures of 1,2-propanediol carbonate with xylene in the temperature range of (293.15 to 353.15) K

Abstract The densities of binary mixtures formed by 1,2-propanediol carbonate with o -xylene, or m -xylene, or p -xylene were measured in the temperature range of (293.15 to 353.15) K and atmospheric pressure using a vibrating-tube densimeter. The excess molar volumes V m E , partial molar volumes and excess partial molar volumes of two components calculated from the density data provide the temperature dependence. The V m E results were correlated using the fourth-order Redlich–Kister equation, with the maximum likelihood principle being applied for the determination of the adjustable parameters. It was found that the V m E in these systems studied increases with rising temperature.
