The ionic liquid methyl trioctylammonium bis(trifluoromethylsulfonyl)imide ([MOA] + [Tf 2 N] À) was used for three of the five binary systems studied. The binary systems were ([MOA] + [Tf 2 N] À + 2-pro-panol or 1-butanol or 2-butanol) and (1-butanol or 2-butanol + ethyl acetate). The ternary systems were {methyl trioctylammonium bis(trifluoromethylsulfonyl)imide + 2-propanol or 1-butanol or 2-buta-nol + ethyl acetate}. The binary and ternary excess molar volumes for the above systems were calculated from the experimental density values for each temperature. The Redlich–Kister smoothing polynomial was fitted to the binary excess molar volume data. Virial-Based Mixing Rules were used to correlate the binary excess molar volume data. The binary excess molar volume results showed both negative and positive values over the entire composition range for all the temperatures. The ternary excess molar volume data were successfully correlated with the Cibulka equation using the Redlich–Kister binary parameters.
The densities of the ternary systems {methyltrioctylammonium bis(trifluoromethylsulfonyl)imide + ... more The densities of the ternary systems {methyltrioctylammonium bis(trifluoromethylsulfonyl)imide + ethanol + methyl acetate, or ethyl acetate} have been measured at the T = (298.15, 303.15, and 313.15) K. The ionic liquid (IL) methyltrioctylammonium bis(trifluoromethylsulfonyl)imide ([MOA]+[Tf2N]−) was used. The ternary excess molar volumes, V123E, were calculated from the experimental densities at each temperature. The V123E values are negative for all mole fractions of the IL. For the system {[MOA]+[Tf2N]− + ethanol + methyl acetate}, the minimum ternary excess molar volume, V123minE, decreases with decreasing z values (increasing mole fraction of IL) except at z = 0.10 at T = 298.15 K. The V123minE decreases with an increase in the temperature except at z = 4.00 at T = 303.15 K. For the system {[MOA]+[Tf2N]− + ethanol + ethyl acetate} V123minE increases with decreasing z values at each temperature. The V123minE decreases with an increase in the temperature except at z = 0.40 at T = 313.15 K and at z = 0.08 at T = (303.15 and 313.15) K where it increases. The Cibulka equation was used to correlate the ternary V123E data using the Redlich–Kister parameters obtained from fitting the Redlich–Kister equation to the five binary systems obtained from literature.
