Description

Description générale

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

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).
• To prepare diethanolamine substrate buffer.
• To prepare a pH10 buffer solution along with MgCl₂ for the incubation of cell lysates extracted from astrocyte cultures.

It may be used in the following processes:

• Preparation of disodiumiminodiacetic acid by dehydrogenation.
• As a solvent and reactant in triazine based dendrimer synthesis.
• Preparation of diethanolamine ionic liquids employed in green Heck reaction.
