外文摘要：Densities of binary mixtures of o-xylene, or in-xylene, or p-xylene with N,N-dimethylformamide have been measured over the full range of compositions at atmospheric pressure and various temperatures by means of a vibrating-tube densimeter. The excess molar volume V-m(E), calculated from the density data, provides the temperature dependence of V-m(E), in the temperature range (293.15 to 353.15) K. The V-m(E) results were correlated using the fourth-order Redlich-Kister polynomial equation, with the maximum likelihood principle being in applied for the determination of the adjustable parameters. Partial molar volumes and excess partial molar volumes of two components were also calculated. It was found that the V-m(E) in the systems studied increase with rising temperature.
