2-Hydroxyethylammonium Carboxylates - Highly Biodegradable and Slightly Toxic Ionic Liquids

Highly hydrophilic ionic liquids easily form in reactions between 2-hydroxyethyl amines and carboxylic acids. They have low toxicity and high biodegradability, serve both as reaction solvents and catalysts in condensation reactions, and they may be reused several times without any purification.
