Ternary liquid-liquid equilibrium of methanol + isopropyl acetate/methyl methacrylate + 1-methylmidazole hydrogen sulfate at different temperatures and 1 atm

The separation of isopropyl acetate/methyl methacrylate and methanol azeotropes is very important for recycling resources and protecting the environment. Ionic liquids (ILs) as excellent solvent are widely studied in recent years. This work investigates the feasibility for separating the isopropyl acetate/methyl methacrylate and methanol azeotropic mixtures using ionic liquid as solvent by liquid-liquid extraction. The two ternary systems of...
