Physical properties of binary mixtures of (t-butyl methyl ether plus alcohols) from T=288.15 K to T=298.15 K
Physical properties such as density, refractive index, and speed of sound of the binary mixtures {x(CH3)(3)COCH3 + (1 -x)CH3OH}, {x(CH3)(3)COCH3 + (1 - x)C2H5OH}, {x(CH3)(3)COCH3 + (1 - x)C3H7OH}, and {x(CH3)(3)COCH3 + (1 - x)C4H9OH} from T = 288.15 K to T = 298.15 K and atmospheric pressure have been measured over the entire composition range x of the mixtures. Excess molar volumes, changes of refractive index on mixing, and deviation in isentropic compressibility for the above systems were calculated and fitted with the Redlich-Kister equation to estimate the fitting parameters and the root-mean-square deviations between calculated and experimental data. Excess molar volumes were fitted as a function of the mole fraction, with temperature and their root-mean-square deviations shown. Values of partial excess molar volumes at infinite dilution are also calculated.
