Abstract

It has been frequently said that onset temperatures obtained from dynamic thermogravimetric analysis can be used to estimate the short-term thermal stability of materials and also the relative thermal stability [1-3].

In this work the relative thermal stability was studied through dynamic analysis under the same experimental conditions for 50 Ionic Liquids (ILs). Several families with fixed anions and different cations and vice versa were chosen to have a comprehensive knowledge of thermal properties of ILs depending on the ions selection. Non-isothermal scans were performed under air atmosphere and a heating rate of 10 K · min-1 for all the selected ILs.

It was observed that the anion influence on the thermal stability is stronger than the cation one, being ILs with [NTf2]- and [OTf]- anions the most stable; meanwhile dicyanamide, nitrate and acetate based ILs were the least stable.
