“…This result comes from the very low residual error (AAD % = 0.009) in the representation of the pure fluids and of the measured mixture density values with the MLFN model. Figure shows also a comparison with the excess volumes measured by Sakurai, Egorov et al, and Boned et al A good agreement between the excess molar volumes predicted by the MLFN density model and the cited experimental data can be noted.…”

Compressed and Saturated Liquid Densities for the 2-Propanol + Water System

2008

View full text Add to dashboard Cite

Compressed liquid densities for the 2-propanol (1) + water (2) mixture have been determined at (300, 325, and 350) K and x 1 close to 0.25, 0.49, and 0.73 using a vibrating tube densimeter. Liquid densities have been measured from about atmospheric pressure up to 10 MPa and correlated with a multilayer feedforward neural network. The composition dependence of the excess molar volume has been evaluated in the temperature and pressure range of the experimental data. A model based on a multilayer feedforward neural network function combined with the saturated pressure equation of the pure fluids has been regressed on the available literature data for the bubble pressure. The correlations for liquid density and bubble pressure have been used to generate the saturated liquid density surface in the whole temperature range of the measured compressed liquid densities and for compositions ranging from the pure 2-propanol to the pure water.

The effect of pressure and temperature on the densities of mixtures of propan-2-ol (1) + n-octane (2)/n-decane (2) was measured using an Anton Paar DMA HP densimeter and a pressurizing circuit. Measurements were conducted for the entire composition range of the mixtures and pure propan-2-ol in the range of 0.1−20 MPa (21 pressure permutations) and six temperatures in the range of 303.15−353.15 K. The data were correlated by the empirical modified Toscani−Szwarc equation of state with five parameters for each composition. The excess molar volume, thermal expansivity, and isothermal compressibility were derived from the experimental data and the regressed model parameters.

“…The AAD with respect to the 428 points including those measured and shown in the literature is about 0.1%.
