ABSTRACT

Density (q), speed of sound (u), and refractive index (nD), values have been measured for the binary mixture of diethyl carbonate (1) and 2-alkoxyethanols (2) over the entire range of mole fraction at intervals of 5 C temperatures from T = (298.15 to 323.15) K under atmospheric pressure (0.1 MPa). Using the basic experimental values, excess molar volume oVE m P, excess isentropic compressibility ojEs P, excess molar isentropic compressibility oKEs ;m P, excess speed of sound (uE), deviation in refractive index oD/nDP and deviation in molar refraction oDRMP of liquid mixtures have been calculated. The excess values have fitted to the Redlich Kister smoothing polynomial equation to estimate the binary coefficients and standard deviation between the experimental and calculated values. The excess partial molar volume, VE m;1, VE m;2 over the whole composition range; and partial molar volume, Vm;1, Vm;2 excess partial molar volume at infinite dilution, Vm; 1E;1 ; VE;1 m;2 have also been calculated. The variations of these parameters with composition and temperature have discussed in terms of intermolecular interactions prevailing in these mixtures.
