一般描述

四乙烯五胺,又称四乙五胺,是一种N5结构的多胺配体,常用作氮前体以合成氧还原反应(ORR)的金属催化剂。 [1] [2]

应用

四乙烯五胺(TEPA)可用作以下反应中的试剂:      
  • 用于功能化修饰2,5-二羟基对苯二甲酸镁(Mg-MOF-74) 以改善材料的CO2吸附性能。
  • 修饰磁性壳聚糖树脂以生成可高效去除水溶液中铀的含胺壳聚糖。
  • 合成聚氯乙烯/四乙烯五胺(PVC-TEPA) 复合材料,其可用作Knoevenagel缩合反应的高效催化剂。

    Postsynthetic functionalization of magnesium 2,5-dihydroxyterephthalate (Mg-MOF-74) with tetraethylenepentamine (TEPA) resulted in improved CO2 adsorption performance under dry and humid conditions. XPS, elemental analysis, and neutron powder diffraction studies indicated that TEPA was incorporated throughout the MOF particle, although it coordinated
