ABSTRACT

The experimental data of the ternary 2-methyl-2-propanol + cyclohexylamine + n-heptane (densities ? and refractive indices nD data) and three binary systems: 2-methyl-2-propanol + cyclohexylamine (nD data), 2-methyl-2-propanol + n-heptane (? and nD data), and cyclohexylamine + n-heptane (nD data) have been determined. Experimental ? and nD measurements have been performed simultaneously, at five temperatures, (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, with a refractometer Anton Paar RXA 156. Excess molar volumes VE and deviations of refractive indices ?nD were correlated by the Redlich-Kister equation for binary mixtures and the Nagata-Tamura equation for the ternary mixture.
