2. Classification of ionic liquids

Ionic liquids are classified according to the following characteristics:

  • protic or aprotic character;

  • sensitivity to water and oxygen;

  • the special characteristics of anions ;

  • toxicity and potential impact on the environment.

2.1 Protic/aprotic character

An ionic liquid is protic if it results from the transfer of a proton from an acid to a base in the Bronsted sense, and if the proportion of non-ionized salt in the liquid state is less than 1%.
