- Abstract:
- Several new branched ionic liquids were synthesized under microwave irradiation applying two
different synthetic approaches. Different already known ionic liquids, both linear and branched, were
added to this set of new ionic liquids to investigate the influence of the branching on the thermophysical
properties to elucidate first structure–property relationships. Thermogravimetric analysis was utilized
to investigate the decomposition behavior and differential scanning calorimetry was used to study the
influence of the branching on the thermal behavior, e.g. the melting point, the glass transition
temperature, the freezing point and the cold crystallization temperature. Moreover, the water uptake
of selected ionic liquids was analyzed.
