Popis: 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, κ s E , excess speeds of sound, u E , excess molar isentropic compressibility, K s , m E , excess isobaric thermal expansion, α p E . 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 , 1 ° E and V ¯ m , 2 ° E ; excess partial molar isentropic compressibilities, K ¯ s , m , 1 ° E and K ¯ s , m , 2 ° E of the components at infinite dilution also been measured.
