Densities, refractive indices, speeds of sound, and shear viscosities of diethylene glycol dimethyl ether with ethyl acetate, methyl benzoate, ethyl benzoate, and diethyl succinate in the temperature range from 298.15 to 318.15 K

AbstractThe speeds of sound has been obtained at a frequency of 4 MHz in diethylene glycol dimethyl ether + methanol, + ethanol, + 1-butanol, and + 1-pentanol across the entire composition range, at the temperature 298.15 K and atmospheric pressure using a NUSONIC velocimeter based on the sing-around technique. The ultrasonic speed values have been combined with those of the excess molar volumes converted to densities to obtain estimates of the product K

Densities, refractive indices, speeds of sound and viscosities of the diethylene glycol dimethyl ether - methyl salicylate system were measured as a function of mole fraction at 298.15, 303.15, 308.15, 313.15 and 318.15 K. The results are fitted by a power series equation involving both the temperature and mole fraction variables. The basic physical data of the mixtures are further used to calculate the excess molar volume VE, changes in isentropic compressibility ∆β, changes in refractivity ∆R and changes in viscosity ∆η. The results are fitted by the Redlich-Kister polynomial relation. The isobaric thermal expansion coefficients of the mixtures are also determined from density measurements. The data are compared with those obtained from equations derived by differentiation of the Lorentz-Lorenz and Eykman relations. Refractive indices of the mixture are used to test the validity of mixing relations. The changes in isobaric thermal expansion coefficients ∆α of the mixtures were examined. Viscosity data were tested in terms of the McAllister, Heric and Auslaender relations.
