Measurement and prediction of excess molar enthalpies of ternary working solutions 1-butyl-3-methylimidazolium dibutylphosphate + methanol/ethanol + water
The excess molar enthalpies of binary and ternary working solutions containing ionic liquid,1-butyl-3-methylimidazolium dibutylphosphate,(1)+ CH3OH(2)/C2H5OH(2)/H2O(2)and(1)+ CH3OH(2)/C2H5OH(2)+ H2O(3)were measured with an adiabatic calorimeter at 298.15 K under the normal atmospheric pressure.The experimental excess molar enthalpies of binary working solutions were correlated with non-random two liquid(NRTL)activity coefficient model,and the binary interaction parameters were obtained.The average relative ...
