Název v původním jazyce

Micelle formation of alkylimidazolium ionic liquids in water and in ethylammonium nitrate ionic liquid: A calorimetric study

Popis výsledku v původním jazyce

Using isothermal titration calorimetry heats of dilution of the aqueous ionic liquid solutions [C4MIM][C8SO4], [C12MIM]Cl, [C16MIM][BF4], and [C16MIM]Cl have been measured in the concentration range of (1?80, 1?35, 0.2?2.2, and 0.1?2.6)mmol.dm-3 respectively at different temperatures between 283K and 338 K. Formation of micelles has been observed. The CMC, the equilibrium constant of micellization as well as the enthalpy of micellization has been determined from the experimental data using a mass-actionmodel with 3?5 parameters adjusted to the experimental data points of the heat of dilution over the whole concentration range. Three modified versions of the model have been tested providing similar results with exception of [C16MIM][BF4] solutions where one of the versions failed. The consistency of the model has been tested by comparing the model parameters of our own experimental results of Na[C12SO4] solutions with those obtained from experimental data of other authors in the litera
