| Abstract | Liquid-liquid extraction with triethylene glycol as solvent, water as cosolvent, and hexane as counter-solvent is being investigated as a process for the separation of phenolic compounds from neutral oils and nitrogen bases. To this end, liquid-liquid equilibria at 313.15 K and atmospheric pressure have been determined for the systems triethylene glycol + hexane + water + (phenol + aniline + benzonitrile + 5-ethyl-2-methyl pyridine + mesitylene) or (m-cresol + o-tolunitrile + o-toluidine + indene + pseudocumene + undecane) or (2,4-xylenol + 3,4-xylenol + 3,5-xylenol + indane + naphthalene + dodecane). From the experimental results it is concluded that triethylene glycol, hexane, and water are effective solvents for the separation of phenolic compounds from neutral oils and nitrogen bases by means of liquid-liquid extraction. LLE binary parameters for the NRTL equation were obtained for each of the three systems by regression of the equilibrium data. The NRTL equation fit the experimental data with a root-mean-square-deviation (RMSD) of 0.0037, 0.0100, and 0.0058 for the systems containing phenol, m-cresol, and the xylenol isomers, respectively. |
