一般描述

四甲基氯化铵是一种季铵盐，由于其热稳定性和对强碱水溶液或亲核试剂的耐受性，通常用作催化剂。

应用

四甲基氯化铵与 N-羟基邻苯二甲酰亚胺和氧杂蒽酮可作为碳氢化合物有氧氧化生成相应含氧化合物的高效氯化物催化体系。它也可作为相转移催化剂，通过活性芳基氯化物与氟化钾在固-液相中的选择性氯/氟交换反应合成芳基氟化物。

A solid understanding of the molecular-level mechanisms responsible for zeolite crystallization remains one of the most challenging issues in modern zeolite science. Here we investigated the formation pathway for high-silica LTA zeolite crystals in the simultaneous presence of tetraethylammonium (TEA(+))...

Biological functions depend on biomolecular assembly processes. Assemblies of lipid bilayers, actins, microtubules, or chromosomes are indispensable for cellular functions. These hierarchical assembly processes are reasonably predictable by understanding chemical structures of the defined building blocks and their interactions. However...
