2021
In the present paper, densities, speeds of sound, and viscosities of four binary mixtures containing the ionic liquids 1-ethyl-3-methylimidazolium methylsulfate and 1-ethyl-3-methylimidazolium thio...
Separation of the azeotropic mixture 2-propanol + water employing different imidazolium ionic liquids as solvents
2020
Abstract The liquid-liquid equilibria of the ternary systems water (1) + 2-propanol (2) + [emim][Tf2N] (3) and water (1) + 2-propanol (2) + [hmim][Tf2N] (3) at 283.2, 303.2 and 323.2 K and atmospheric pressure were investigated, in order to achieve a better knowledge of the ternary mixture behaviour. The capability of [emim][Tf2N] and [hmim][Tf2N] as solvents in the separation of the azeotropic mixture water + 2-propanol was studied through the distribution coefficient and selectivity, and compared with the results obtained with other ionic liquids in the same azeotropic mixture studied before by our research group. The thermodynamic parameters of both ternary mixtures were calculated by th…
