Bis(2-hydroxyethyl)ammonium formate

Ionic liquids such as bis(2-hydroxyethyl)ammonium formate are proving to be ideal adsorbents for acidic gases such as CO2 or SO2. Compared to volatile adsorbents such as amines, which evaporate easily; or their caustic counterparts (calcium carbonate, calcium oxide, sodium hydroxide, etc.), ionic liquids provide favorable properties such as extremely low vapor pressure, high thermal stability, and chemical stability, as well as excellent solvent ability for organic and inorganic compounds. In addition, bis(2-hydroxyethyl)ammonium formate is useful ingredient in the development of new solvent used in mineral and biorefinery processes, reaction chemistry, etc.
