The liquid-liquid equilibrium was measured at 20 °C in the title quaternary system and in the three nitromethane-containing ternary subsystems. The data were compared with those predicted by a superposition of the Wilson and Redlich-Kister equations including the ternary parameters. The agreement between the observed and calculated data is very good both for the quaternary system and for the three ternary systems.
