Abstract
The object of the present work is to evaluate the use of toluene as an alte rnative solvent for nicotine extraction from aqueous-leached solutions of t obacco wastes. The liquid-liquid equilibrium data of the ternary system wat er + toluene + nicotine has been determined at 295, 303, and 313 K. The res ults have been correlated using the UNIQUAC and NRTL equations with linear temperature-dependent parameters. It is concluded that toluene is an effect ive agent for nicotine extraction.
