General description

2-(Diethylamino)ethanol (DEEA) is a tertiary alkanolamine multi-component aqueous solvent. It has a high chemical stability and resistance against degradation. DEEA is used to prepare quaternary ammonium salts. These salts are widely used as phase transfer catalysts to promote reactions between immiscible phases.

Application

2-(Diethylamino)ethanol (DEEA) can be used as a co-solvent with methyldiethanolamine (MDEA) and sulfolane to investigate the CO2 absorption and desorption behavior in aqueous solutions. Additionally, DEAE is used to prepare N-substituted glycine derivatives and these compounds are used in the synthesis of peptides and proteins.
