ABSTRACT

The densities of binary mixtures formed by nitrobenzene with benzene, or toluene, or ethylbenzene, or styrene, or o-xylene, or m-xylene, or p-xylene + nitrobenzene were measured in the temperature range of (293.15 to 353.15) K and ambient pressure using a vibrating-tube densimeter. The excess molar volumes V E m, partial molar volumes and excess partial molar volumes of two components calculated from the density data provide the temperature dependence. The V E m 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 E m in these systems studied increase with rising temperature.
