Anwendungen & Verwendung
Verwenden
Iminodiacetic acid can be used:In the preparation of iminodiacetic acid (IDA)-type adsorbent for protein purification.As a catalyst along with iron (FeCl3) complexes for methyl methacrylate (MMA) polymerization. In the preparation of chelating resins with glycidyl methacrylate for the selective removal and recovery of metal ions from industrial waste water.As a reagent for the preparation of pinene-derived iminodiacetic acid (PIDA), which is in turn used as a ligand for the synthesis of diastereoselective oxiranyl C(sp3) boronates from the corresponding olefins.In the surface functionalization of multi-walled carbon nanotubes (MWCNTs) which is further utilized as a sorbent for the separation of heavy metal ions.
