How can Ionic Liquids be disposed?
Ionic Liquids are frequently reported as being non-flammable. This is only true up to the temperatures at which decomposition takes place. Some Ionic Liquids already start to decompose at 120°C others are stable up to nearly 400°C. Upon decomposition neutral and volatile molecules are formed which of course can burn. This explains why Ionic Liquids indeed have flash points even if they are usually much higher than 100°C. However, Ionic Liquids can easily be disposed by incineration which is usually done at temperatures of several hundred degrees celsius. At these very high temperatures even the toughest organic Ionic Liquids will give up.
