摘要/Abstract

摘要： On the basis of reported experimental vapor-liquid equilibrium (VLE) data of NH₃-1-ethyl-3-methylimidazolium acetate (NH₃-[Emim]Ac), NH₃-1-butyl-3-methylimidazolium tetrafluoroborate (NH₃-[Bmim][BF₄]), NH₃-1,3-dimethylimidazolium dimethyl phosphate (NH₃-[Mmim]DMP) and NH₃-1-ethyl-3-methylimidazolium ethylsulfate (NH₃-[Emim]EtOSO₃) binary systems, the interaction parameters of 14 new groups have been regressed by means of the UNIFAC model. To validate the reliability of the method, these parameters have been used to calculate the VLE data with the average relative deviation of pressures of less than 9.35%. The infinite dilution activity coefficient (γ₁^∞) and the absorption potential (Ψ₁) are important evaluation criterions of the affinity between working pair species of the absorption cycle. The UNIFAC model is implemented to predict the values of γ₁^∞ and Ψ₁ of 16 sets of NH₃-ionic liquid (IL) systems. The work found that the Ψ₁ gradually increases following the impact order: Ψ₁([C_nmim][BF₄])<Ψ₁([C_nmim]EtOSO₃)<Ψ₁([C_nmim]DMP)<Ψ₁([C_nmim]Ac) (n=1, 2, 3,...) at a given cation of IL species and constant temperature, and <Ψ₁([Mmim]X)<Ψ₁([Emim]X)<Ψ₁([Pmim]X)<Ψ₁([Bmim]X) (X=Ac, [BF₄], DMP or EtOSO₃) at a given anion of IL species and constant temperature. Furthermore, the Ψ₁ gradually increases with increasing temperature. Then, it could be concluded that the working pair NH₃-[Bmim]Ac has the best potential research value relatively.
