一般描述
氯化铵晶体（NH4Cl）属于立方晶系。可以通过HCl与氨水溶液反应来合成。NH4Cl在通过Solvay工艺制造苏打过程中，可作为副产物形成。
应用
氯化铵（NH4C1）已被用作红细胞（RBC）裂解缓冲液的成分之一，可用于多种研究中。它可以用作制备3，4-二氢嘧啶-2-（1H）-酮的催化剂。
无机铵离子（NH4+）可有效地催化羰基化合物的羟醛缩合。在制备三甲胺盐酸盐（TMA·HCl）时，它可用作氮源。

In natural environments such as atmospheric aerosols, organic compounds coexist with inorganic salts but, until recently, were not thought to interact chemically. We have recently shown that inorganic ammonium ions, NH(4)(+), act as catalysts for acetal formation from glyoxal, a
