Beschreibung

Allgemeine Beschreibung

N-(2-Hydroxyethyl)iminodiacetic acid (HEIDA) is a biodegradable and strong metal chelating agent, similar to nitrilotriacetic acid (NTA).[1]

Anwendung

N-(2-Hydroxyethyl)iminodiacetic acid (HEIDA) can be used in the following processes:

• HEIDA can be used as a metal chelating agent for Fe(III) ion. The presence of HEIDA improves the Fenton′s destruction performance of PCE (perchloroethylene) existing as dense non-aqueous phase liquid (DNAPL) in soil slurry systems.[1]
• Oxorhenium(V) complexes with HEIDA are used for the carboxylation of ethane by CO, with potassium peroxodisulfate (K₂S₂O₈)/trifluoroacetic acid (TFA), to afford propionic and acetic acid in good yield.[2]
• Vanadium complexes with HEIDA are used for the peroxidative hydroxylation of benzene and oxidation of mesitylene.[3]
