ABSTRACT

This paper reports the experimental values of density, speed of sound and refractive index of binary mixture of (+-)-linalool + ethanol at four temperatures in the range of 283.15 - 328.15 K and 0.1 MPa. Excess molar volume, speed of sound deviation, refractive index deviation, molar refraction, molar refraction deviation and excess isentropic compressibility are also given at the same work conditions. Afterward, prediction of speed of sound and refractive index was carried out using several theoretical models or equations. The experimental density of the binary mixture was measured at high pressure between 20 and 40 MPa in the same range of temperature. Excess molar volume, isobaric thermal expansion, and isothermal compressibility were also calculated. Peng-Robinson (PR), Patel-Teja (PT), the Statistical Associating Fluid Theory (SAFT) and the Perturbed-Chain Statistical Associating Fluid Theory (PC-SAFT) were tested as predictive models of the PrhoT behaviour. The best predictions were obtained with the PC-SAFT equation of state (EOS).
