Density, refractive index, excess molar volumes and deviations in molar refraction at 298.15?K for binary and ternary mixtures of DIPE (OR TAME)?+?1-methanol (or 1-propanol)? plus ?trihexyltetra-decylphosphonium bis (2,4,4-trimethylpentyl) phosphinate
The excess molar volumes (VE) and the deviations in molar refraction (?R) at 298.15?K were determined for the binary systems {diisopropyl ether (DIPE)?+?1-propanol}, {Tert-amyl methyl ether (TAME)?+?methanol}, {DIPE?+?trihexyltetradecylphosphonium bis(2,4,4-trimethylpentyl)phosphinate ([P666,14][TMPP])}, {TAME?+?[P666,14][TMPP]}, {methanol?+?[P666,14][TMPP]} and {1-propanol?+?[P666,14][TMPP]} using a digital vibrating-tube densimeter and a precision digital refractometer. The VE and ?R were correlated with the RedlichKister equation for binary systems. In addition, the ternary VE and ?R data at 298.15?K were predicted for the ternary systems {DIPE?+?1-propanol?+?[P666,14][TMPP]} and {TAME?+?methanol?+?[P666,14][TMPP]} by using the binary contribution model of Radojkovic with correlated sub-binary RedlichKister parameters.
