Abstract: Limiting selectivities and capacities for various compositions of the mixed solvent ethylene glycol (EG)-diethylene glycol (DEG)-N-methylpyrrolidone (NMP) with respect to toluene have been calculated from limiting activity coefficients of toluene and heptane. The calculations were made for both the ideal and real behaviour of the mixed solvent. The limiting activity coefficients of the model hydrocarbons toluene and heptane in the mixed solvent were calculated from experimentally determined binary coefficients…
