Due to the advantages of high temperature stability, low corrosion, and good heat transfer performance, potassium nitrate aqueous solution holds application potential in absorption systems. In order to further improve its absorption ability, ionic liquids (ILS) such as [Emim]Cl, [Emim]Ac, and [Emim]Br were selected as additives. In this paper, vapor pressures of four {KNO3 + ILS + H2O} ternary systems were measured by a dynamic b.p. method, including {KNO3 + [Emim]Cl + H2O}, {KNO3 + [Emim]Ac + H2O}, {KNO3 + [Emim]NO3 + H2O}, and {KNO3 + [Emim]Br + H2O}. Molar ratios between KNO3 and ILs were 1:1 for these systems, and the total absorbent mass fractions were in the range of 0.20 to 0.70. Exptl. data were regressed by Antoine-type equations, and the average absolute relative deviations (AARD%) between the exptl. and calculated values were no more than 0.78%, which showed good consistency of these experiments Vapor-liquid equilibrium behavior of these different ionic liquid ternary systems were compared and [Emim]Ac showed best performance in reducing vapor pressure at relatively higher mass fractions. And 1-Ethyl-3-methyl-1H-imidazol-3-ium chloride (cas: 65039-09-0) was used in the research process.
1-Ethyl-3-methyl-1H-imidazol-3-ium chloride(cas: 65039-09-0) is an imidazolium chloride ionic liquid that can be used as:a starting material for the preparation of 1-ethyl-3-methylimidazolium chloride/tetrafluoroborate (EMI.Cl.BF4) molten salt for electrochemical studies; a solvent as well as catalyst for the depolymerization of oak wood lignin.Recommanded Product: 65039-09-0
