一般說明

Dabco® 33-LV作为叔胺催化剂,在聚合物应用中具有多种用途。它广泛用作催化剂,通过异氰酸酯和多元醇之间的反应生产柔性和刚性聚氨酯泡沫。它可以帮助控制凝胶时间,改善泡沫上升,并优化最终聚氨酯泡沫的物理性质。这些泡沫通常用于绝缘材料、汽车应用、建筑和包装应用。此外,DABCO® 33-LV可以在各种基材上形成自组装单层(SAM),使其成为聚合物领域中的有用双齿配体。

Dabco®33-LV (Db)是一种凝胶催化剂和双齿配体,可以在各种基材上形成自组装单层(SAM)。它可使表面功能化并固定表面原子。

應用

Dabco® 33-LV (Db)可用于:
  • 作为凝胶催化剂,促进柔性和刚性聚氨酯泡沫、微孔泡沫、涂层和弹性体生产中的凝胶反应。Dabco®33-LV用于加速异氰酸酯-多元醇反应。
  • 在通过静电纺丝合成阴离子交换膜(AEM)的过程中,有助于聚合物之间的交联,维持膜的机械稳定性。AEM可进一步用于燃料电池、水电解、氧化还原液流电池和电解槽。
  • Db可用于制备环氧基大豆油,以形成聚氨酯泡沫。

Based on the same working principle as the nontraceless Staudinger Ligation the auxiliary phosphine reagent can be cleaved from the product after the ligation is completed leaving a native amide bond. Thus, the total chemical synthesis of proteins and glycopeptides is enabled overcoming the limitations of native chemical ligation (NCL) of a Cys residue at the ligation juncture.
