ABSTRACT

The density of the asymmetrical binary systems (ethanol + linalool), (propan-1-ol + linalool), and (propan-2-ol + linalool) has been measured (660 points) for nine different compositions including the pure compounds at four temperatures in the range (283.15 to 328.15) K and 5 isobars up to 20 MPa with a vibrating-tube densimeter. The experimental expanded uncertainty is estimated to be +- 0.5 kg*m-3. The isothermal compressibility, the isobaric thermal expansion, and the excess molar volume were derived from the experimental density data, revealing that a volume contraction occurs for these binary mixtures. Three different equations of state (EOS s), Peng-Robinson (PR), statistical associating fluid theory (SAFT), and perturbed-chain statistical associating fluid theory (PC-SAFT), were applied to predict the volumetric behavior of the alkanolic mixtures. The best predictions were achieved with the PC-SAFT equation of state.
