一般描述
NH4Cl是一种高度腐蚀性的无色盐，易溶于水。它能以八面体的羽毛状阵列从水溶液中结晶出来，形成纤维状晶体。它在340oC可发生升华。 氯化铵可在醛、1,3-二羰基化合物与尿素或硫脲的一锅Biginelli缩合反应中充当催化剂。 无机铵离子，NH4+，已报道为羰基化合物羟醛缩合反应的有效催化剂。NH4Cl已报道可以提高氢化镁的水解速率，降低氢化镁在制氢过程中的活化能。

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

羟醛缩合反应是由Charles Wurtz推出的有机反应，他于1872年首次从乙醛中制备了β-羟基醛。
The aldol condensation reaction is an organic reaction introduced by Charles Wurtz, who first prepared the β-hydroxy aldehyde from acetaldehdye in 1872.
