ABSTRACT

The densities of dimethyl carbonate, cyclohexane, and their mixtures were measured for nine compositions at five different temperatures varying from (293.15 to 313.15) K and over the pressure range of (0.1 to 40) MPa. The densities of pure substances and their mixtures at atmospheric pressure were measured with a vibrating-tube densimeter. The densities at elevated pressures were measured with a high-pressure apparatus and a precise analytical balance. The molar volumes Vm, excess molar volumes VmE, isothermal compressibilities ?, and isobaric expansivities a were derived from the experimental densities.
