Effect of Heating Temperature on the Flash Point of Ionic Liquids

The ionic liquids are considered to be a green chemical because of their thermal stability and low volatility. This research investigated the flash point variation of ionic liquids after heat treatment at different temperature. Thermogravimetric analysis (TGA), Fourier Transform Infrared Spectroscopy FTIR) and Flash point analyser were used to analyze the thermal stability of ionic liquids. The ionic liquids, [C6mim] [Cl] and [C2mim] [NTf2] were selected as tested samples. The results indicated that the flash point of the ionic liquids was affected by the temperature of heat treatment, owing to the thermal decomposition of ionic liquids, therefore.
