一般描述

三乙胺(TEA, Et3N)是一种脂肪族胺。将它添加到基质辅助激光解吸/电离(MALDI)基质中,可在MALDI质谱(MS)成像过程中为透明的液体基质提供增强的空间分辨能力。一种用于测定活性药物成分中的三乙胺的顶空气相色谱(GC)过程已被报道。在一定密度和温度范围内三乙胺蒸汽的粘度系数已得到测量。

应用

三乙胺已用于以下合成过程:
  • 5′-二甲氧基三苯甲基-5-(呋喃-2-基)-2′-脱氧尿苷
  • 3′-(2-氰乙基)二异丙基-5′-二甲氧基三苯甲基-5-(呋喃-2-基)-2'-脱氧尿苷
  • 聚乙胺600-β-环糊精(PEI600-β-CyD)
它还可通过甘油和碳酸二甲酯(DMC)之间的酯交换反应用作制备二碳酸甘油酯的均相催化剂。
