ABSTRACT

Molar heat capacities, Cp, densities, F, dynamic viscosities, e, and refractive indices, nD, for the binary mixtures dimethyl sulfoxide (DMSO) + tetrahydropyran (THP) and + 2-methyltetrahydrofuran (MTHF) were determined at (293.15, 303.15, and 313.15) K using a Perkin-Elmer differential scanning calorimeter, an Anton Paar density meter, a Schott-Gerate AVS unit, and an Abbe refractometer, respectively. Excess molar volumes, Vm E , deviations of the dynamic viscosities, centse, and deviations of the refractive indices, centsR, were calculated at these temperatures. These properties were fitted to the Redlich-Kister equation.
