General description

Diethanolamine (DEA) is an amino alcohol commonly used in the preparation of soaps and surfactants, agricultural chemicals and in textile processing.^[2] It is used as an absorbent for capturing CO₂.^[3] Its toxic and carcinogenic effect has been studied.^[2]

Application

Diethanolamine has been used:
• As a solvent and stabilizer to synthesize zinc oxide (ZnO): indium (In) thin film, which was employed as photoanode in dye synthesized solar cell (DSSC).^[4]
• To prepare diethanolamine substrate buffer.^[5]
• To prepare a pH10 buffer solution along with MgCl₂ for the incubation of cell lysates extracted from astrocyte cultures.^[1]
It may be used in the following processes:
• Preparation of disodiumiminodiacetic acid by dehydrogenation.^[6]
• As a solvent and reactant in triazine based dendrimer synthesis.^[7]
• Preparation of diethanolamine ionic liquids employed in green Heck reaction.^[8]
