摘要：

Tie lines and liquid-liquid equilibrium data are presented for mixtures of an n-alkane + toluene + N-methyl-2-pyrrolidone and. mixtures of n-hexadecane + an aromatic hydrocarbon + N-methyl-2-pyrrolidone at 298.2 K and 1 atm pressure, n-Alkane refers to n-hexane or n-nonane or n-tetradecane or n-hexadecane, and an aromatic hydrocarbon refers toluene or o-xylene or m-xylene or p-xylene or mesitylene or ethylbenzene. N-methyl-2-pyrrolidone is an important solvent used in the extraction of aromatic compounds from alkane-aromatic mixtures. The data presented here complements data in the literature and gives a broader description of the phase equilibrium properties of the mixtures generated by an n-alkane + an aromatic hydrocarbon and N-methyl-2-pyrrolidone.
