Physical properties of binary mixtures of (t-butyl methyl ether + alcohols) fromT = 288.15K toT = 298.15K

Abstract

Physical properties such as density, refractive index, and speed of sound of the binary mixtures {x(CH3)3COCH3+(1 −x)CH3OH}, {x(CH3)3COCH3+(1 −x)C2H5OH}, {x(CH3)3COCH3+(1 −x)C3H7OH}, and {x(CH3)3COCH3+(1 −x)C4H9OH} fromT= 288.15 K toT= 298.15 K and atmospheric pressure have been measured over the entire composition rangexof 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.
