The studied compounds are based on different anions (imide, triflate, sulphonate, phosphate) and cations (phosphonium, pyridinium, pyrrolidinium, imidazolium, choline) in order to determine possible dependences of these properties according to a selected ion. From the results of DSC and TGA techniques, the liquid range of the selected ILs was estimated using as limits of this interval tm and tonset/t´0.10/10h.engEsta obra atópase baixo unha licenza internacional Creative Commons BY-NC-ND 4.0.
