Liquid–liquid extraction of p -xylene from their mixtures with alkanes using 1-butyl-1-methylmorpholinium tricyanomethanide and 1-butyl-3-methylimidazolium tricyanomethanide ionic liquids

摘要: Abstract Liquid – liquid experimental data for four ternary systems {1-butyl-1-methyl-morpholinium tricyanomethanide, [BMMOR][TCM], or 1-butyl-3-methylimidazolium [BMIM][TCM] + p-xylene + octane, decane} were determined at T = 298.15 K and atmospheric pressure. The separation of p-xylene from alkanes (octane, decane) is performed by extraction with the tricyanomethanide - based ionic liquids. Good miscibility practical complete immiscibility in liquids have been observed. Selectivity, S solute distribution ratio, β constant temperature these mixtures calculated discussed. These parameters derived equilibrium compared values other available literature. NRTL UNIQUAC models used to correlate LLE data. Agreement between correlated was satisfactory. influence cation structure on phase ability Additionally, water content basic physicochemical properties, such as: density, ρ dynamic viscosity, η pure ILs wide range ambient
