This work discusses the densities and speeds of sound of binary mixtures of 1- butyl -3-methylimidazolium Tetrafluroborate ionic liquid with Ethyl acetate at different temperatures. Molecular interactions and the effect of temperature on interactions are analyzed through excess properties such as excess molar volumes, excess isentropic compressibility, excess speeds of sound, excess molar isentropic compressibility, and excess isobaric thermal expansion. The experimental results are adequately fitted with the Redlich-Kister polynomial equation.
In this work, densities and speeds of sound of binary mixtures of 1- butyl -3-methylimidazolium Tetrafluroborate ionic liquid (IL) with Ethyl acetate (EtOAc) have been measured at temperatures 298.15 - 323.15 K at atmospheric pressure. With the help of experimental results, a discussion is carried out on the molecular interactions and the effect of temperature on interactions through excess properties such as excess molar volumes, V-m(E), excess isentropic compressibility, kappa(E)(s), excess speeds of sound, u(E), excess molar isentropic compressibility, K-s,m(E), excess isobaric thermal expansion, alpha(E)(p). The excess properties are adequately fitted with the Redlich-Kister polynomial equation. The excess partial molar volumes, V-m,1(-E) and V-m,2(-E); excess partial molar isentropic compressibilities, K-s,m,1(-E) and K-s,m,2(-E); excess partial molar volumes, V-m,V-1 and V-m,V-2; excess partial molar isentropic compressibilities, K-s,K-m,K-1 and K-s,K-m,K-2 of the components at infinite dilution also been measured.
