摘要: The density, refractive index, and kinematic viscosity were measured for extraction solvents molybdenum: methyl ethyl ketone (MEK), isopropyl (MIPK), trihexyl tetradecyl phosphonium chloride ([P666,14] [Cl]), dicyanamide ([P666,14][DCA]) bis (2,2,4- trimethyl pentyl) phosphinate ([P666,14][TMPP]) at atmospheric pressure a temperature range of 288.15-318.15 K. experimental data correlated using the Daubert Danner equation, linear equation Goletz Tassion equation. In addition, excess molar volumes (VE) deviations in refractivity (ΔR) 298.15 K reported following binary systems: {MEK+[P666,14][Cl]}, {MEK+[P666,14][DCA]}, {MEK+[P666,14][TMPP]}, {MIPK+[P666,14][Cl]}, {MIPK+[P666,14][DCA]} {MIPK+[P666,14][TMPP]}. determined VE ΔR values with Redlich-Kister density index also predicted several mixing rules, these results then compared data.
