Thermal stability and decomposition mechanism of 1-ethyl-3-methylimidazolium halides

“…The currently found melting temperature for [EMIm]Cl (86 C) was in close agreement with that obtained in DSC measurements earlier [11][12][13]. Likewise, the freezing temperature (33 C) published by Ngo et al [10] covers the upper limit of the crystallization temperature interval obtained in this study.…”

“…Ngo et al [10] investigated thermal properties of several imidazolium ILs including [EMIm]X (X = Cl, Br, I) salts using differential scanning calorimetry with relatively high heating/cooling rates of 10 K min À1 and temperature-ramped thermogravimetric analysis (TGA) performed with a heating rate of 20 K min À1 . Other works [9,[11][12][13][14] only present the melting behavior without systematic studies on crystallization and decomposition.…”

Eutectic mixtures of pyrrolidinium-based ionic liquids

“…to a global minimum in melting point of the mixture at an appropriate molar ratio. [19] Thermodynamic exploration of eutectic mixtures of ILs was the subject of several articles in the literature, [10,20,21,22,23] which focused almost entirely in mixtures of imidazoliumbased ILs. Pyrrolidinium-based ILs are another popular family of ILs, somewhat cheaper than their imidazolium analogues, and with favourable properties such as wide electrochemical windows, of great interest for e.g.…”

Improving Cellulose Dissolution in Ionic Liquids by Tuning the Size of the Ions: Impact of the Length of the Alkyl Chains in Tetraalkylammonium Carboxylate

“…In 2002, for the first time, it was reported that ionic liquids (ILs) could efficiently dissolve cellulose:u pt o 10 wt %c ellulose in ac hloride-basedI La t1 00 8C. [7] Carboxylate-based ILs are liquid at lower temperatures, but suffer from stability issues and should be used below 120 8Cinl ong processes. [5] The process depends not only on the temperature, but also on the cellulose (length of the polymer chains, crystallinity,i mpurities) and on the amount of water in the cellulose itself and in the ILs (highly hygroscopic).…”

“…For example, the meltingp oint of 1-butyl-3-methylimidazolium chloride ([Im 14 ]Cl) is 69 8C. [7] Carboxylate-based ILs are liquid at lower temperatures, but suffer from stability issues and should be used below 120 8Cinl ong processes. [8] The search for new ILs able to dissolve cellulose efficiently remains very active.…”
