- •
Two thiocyanate-based ionic liquids were tested as entrainers to separate n-heptane and toluene.
- •
(Vapor + liquid) equilibrium data were measured at T = (323.2, 343.2, and 363.2) K.
- •
Relative volatility of n-heptane from toluene using ionic liquids was calculated.
- •
VLE data for {n-heptane + toluene + ionic liquid} mixtures were model using NRTL.
- •
Mixtures of [EMim][SCN]/inorganic salts were also tested as entrainers.
