ABSTRACT

The experimental density rho and refractive index nD of the six binary mixtures of dimethylphthalate and dimethyladipate with 1-butanol, 2-butanol and 2-butanone have been determined. All measurements of rho and nD have been performed simultaneously at eight temperatures (288.15, 293.15, 298.15, 303.15, 308.15, 313.15, 318.15 and 323.15) K, and atmospheric pressure, using an Anton Paar DMA 5000 digital vibrating-tube densimeter and Anton Paar RXA 156, respectively. Excess molar volumes and deviations of refractive indices were correlated by the Redlich- Kister equation. In addition, correlation of have been performed with the Peng-Robinson-Stryjek-Vera cubic equation of state (PRSV CEOS) with two different types of mixing rules: the van der Waals (vdW1) and mixing rule introduced by Twu et al. (TCBT). For the refractive index calculations several mixing rules were employed: Lorentz-Lorenz, Dale-Gladstone, Eykman, Arago-Biot, Newton and Oster.
