Liquid‐liquid equilibria for toluene‐heptane‐<i>N</i>‐methyl pyrrolidone and benzene‐heptane solvents

Abstract

Abstract The liquid‐liquid equilibria for toluene‐ n ‐heptane‐ N ‐methyl pyrrolidone containing 10 and 20% water at 298 and 313 K, and of benzene‐ n ‐heptane with N ‐methyl pyrrolidone‐ethylene glycol and γ‐butyrolactone‐ethylene glycol, which is a new solvent combination, have been determined at 303 K.
