ABSTRACT
The densities of the ternary systems {methyltrioctylammonium bis[(trifluoromethyl)sulfonyl]imide + methanol + methyl acetate or ethyl acetate} have been measured at the temperatures (298.15, 303.15, and 313.15) K. The ternary excess molar volumes,V123E, were calculated from the experimental densities at each temperature. The V123Evalues are negative for all mole fractions of the ionic liquid (IL). For the system {[MOA]+[Tf2N]- + methanol + methyl acetate}, the minimum ternary excess molar volumes, V123,minE, decrease with decreasing z values (increasing the mole fraction of the IL) except at z equal to 0.30 at temperatures (298.15 and 313.15) K. The V123,minEdecreases with an increase in the temperature. For the system {[MOA]+[Tf2N]- + methanol + ethyl acetate}, V123,minE increases with decreasing z values at each temperature. The Cibulka equation was used to correlate the ternary excess molar volume data from the Redlich-Kister parameters obtained from fitting the Redlich-Kister equation to the five binary systems obtained from the literature. There is a good correlation between the Cibulka equation and experimental V123Edata.
