Descrição geral

Tetraethylenepentamine, also known as Tetrene, is a N5-structure polyamines ligand, often used as a nitrogen precursor to synthesize metal catalysts during oxygen reduction reaction (ORR).

Aplicação

Tetraethylenepentamine (TEPA) can be used as a reagent:      
  • To functionalize magnesium 2,5-dihydroxyterephthalate (Mg-MOF-74) to enhance the CO2 adsorption performance of the material.
  • To modify magnetic chitosan resin to form amine-bearing chitosan for the efficient removal of uranium from an aqueous solution.
  • To synthesize poly(vinyl-chloride)/tetraethylenepentamine (PVC-TEPA) composite material, which is used as an efficient catalyst for the Knoevenagel condensation reaction.
