摘要: Abstract This work presents the thermophysical properties and structure of N-methyl-2-pyrrolidone (NMP) in binary mixtures with 1-alkyl-3-methyl imidazolium cation [amim]+ different anions (chloride, methyl sulfate tetrafluoroborate) ionic liquids (ILs). A comprehensive set such as densities (ρ), ultrasonic sound velocities (u) viscosities (η) have been measured at temperature range from 298.15 to 313.15 K over whole concentration ILs under atmospheric pressure. The used for present study included 1-ethyl-3-methylimidazolium methylsulfate [Emim][MeSO4], 1-butyl-3-methylimidazolium tetrafluoroborate [Bmim][BF4], 1-ethyl-3-methyl chloride [Emim][Cl] [Bmim][Cl] family ILs. From these experimental data, excess molar volume (VE), deviation isentropic compressibility (Δκs) viscosity (Δη) were calculated adequately correlated by using Redlich–Kister polynomial equation. data interpreted on basis intermolecular interactions structural effects between like unlike molecules upon mixing.
