ABSTRACT

The experimental density and refractive index nD data have been determined for the systems of dicyclohexilamine with 1-propanol, or 1-butanol, or 2-butanol, or 1-pentanol, in the temperature range (288.15, 293.15, 298.15, 303.15, 308.15, 313.15, 318.15 and 323.15) K, and at (303.15, 308.15, 313.15, 318.15 and 323.15) K for the system 2-methyl-2-propanol + dicyclohexylamine. All measurements have been performed at atmospheric pressure, using an Anton Paar DMA 5000 digital vibrating tube densimeter and with a refractometer Anton Paar RXA 156. Excess molar volumes and deviations of refractive indices AnD were correlated by the Redlich-Kister equation. Also, correlation of have been performed with the Peng-Robinson-Stryjek-Vera cubic equation of state (PRSV CEOS) coupled with the van der Waals (vdW1) and mixing rule introduced by Twu et al. (TCBT). In addition, several different mixing rules were employed for refractive index calculations: Lorentz- Lorenz, Dale-Gladstone, Eykman, Arago-Biot, Newton and Oster.
