摘要: Abstract The experimental data on density and vapor pressure for nonaqueous solution of ionic liquids are important not only the design optimization chemical processes, but also from theoretical perspective to predict physical properties modeling under different conditions. In this study, solutions liquid, 1-ethyl-3-methylimidazolium ethyl sulfate [EMIM][ES] in some polar organic solvents, i.e. 1-propanol, ethanol methanol, dilute region liquid concentration were measured by use isopiestic method at 298.15 K. regard, Perturbed Chain Statistical Association Fluid equation state (PC-SAFT) is used prediction investigated systems. obtained results PC-SAFT provide reliable accurate predictions with absolute average deviations (AAD), 0.01 0.084 , respectively.
