ABSTRACT

The liquid range of six Ionic Liquids (ILs) with potential uses in biological applications was determined. The lower limit, given by solid-liquid transitions, was determined using differential scanning calorimetry (DSC). The transitions of four ILs were reported for first time, others have shown good agreement with literature values. The upper limit of the liquid range was determined using thermogravimetric analysis (TGA). Dynamic and isothermal methods have been combined to estimate the maximum operation temperature. Dry air and inert atmosphere were attempted with no significant differences between the obtained data. Results are in good agreement with the scarce information found in literature while in most cases upper limit of the liquid range was studied for first time. Measures throw interesting information on cation and anion effect over the studied properties.
