Thermodynamic modelling of liquid-liquid extraction of naphthenic acid from dodecane using imidazolium based phenolate ionic liquids

In this work, N-alkyl imidazolium based ionic liquids with phenolate anions have been used for the separation of naphthenic acid from model oil. The liquid-liquid equilibrium (LLE) data for the ternary mixture of CnmimPhe, dodecane and naphthenic acid were experimentally obtained at a constant tempe...

The liquid-liquid equilibrium (LLE) data for the ternary mixture of CnmimPhe, dodecane and naphthenic acid were experimentally obtained at a constant temperature of 303.15 K and atmospheric pressure.
