Binary Mixture Properties of Methyl tert-Butyl Ether with Hexane or Heptane or Octane or Nonane from 288.15 K to 298.15 K

Abstract

Density, refractive index, and speed of sound of the binary mixtures methyl tert-butyl ether + hexane or heptane or octane or nonane from 288.15 K to 298.15 K and at atmospheric pressure have been measured over the whole composition range of mixtures. Excess molar volumes, changes of refractive index on mixing, and deviations in isentropic compressibility for the binary systems were fitted as a function of the mole fraction and temperature, and their root mean square deviations are shown. The excess molar volumes have been compared with the results from Prigogine−Flory and Prigogine−Flory−Patterson theories. Excess partial molar volumes and those corresponding to the infinite dilution condition are also calculated.
