Description

Application

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.
