文摘

The density, refractive index, and kinematic viscosity were measured for extraction solvents for molybdenum: methyl ethyl ketone (MEK), methyl isopropyl ketone (MIPK), trihexyl tetradecyl phosphonium chloride ([P_666,14] [Cl]), trihexyl tetradecyl phosphonium dicyanamide ([P_666,14][DCA]) and trihexyl tetradecyl phosphonium bis (2,2,4- trimethyl pentyl) phosphinate ([P_666,14][TMPP]) at atmospheric pressure for a temperature range of 288.15-318.15 K. The experimental data were correlated using the Daubert and Danner equation, a linear equation and the Goletz and Tassion equation. In addition, the excess molar volumes (VE) and the deviations in molar refractivity (ΔR) at 298.15 K were reported for the following binary systems: {MEK+[P_666,14][Cl]}, {MEK+[P_666,14][DCA]}, {MEK+[P_666,14][TMPP]}, {MIPK+[P_666,14][Cl]}, {MIPK+[P_666,14][DCA]} and {MIPK+[P_666,14][TMPP]}. The determined VE and ΔR values were correlated with the Redlich-Kister equation. The binary density and refractive index data at 298.15 K were also predicted using several mixing rules, and these results were then compared with the experimental data.
