羟铵盐是一类含质子化羟胺的盐，化合物中存在NH₃OH⁺阳离子。除此之外，[(NH₃OH)₂H]⁺和[(NH₃OH)₃H]⁺也是已知的。^[1]

制备与性质

羟铵盐可由羟胺和酸的中和反应制得^[2]，或通过复分解反应^[3]及配体取代反应^[4]得到：

NH₂OH + CH₃COOH → CH₃COONH₃OH

2 NH₃OHF + H₂SiF₆ → (NH₃OH)₂SiF₆ + 2 HF

NH₃OHCl + VOF₃ + HF → (NH₃OH)VOF₄ + HCl↑

由于NH₃OH⁺具有还原性，它和氧化性阴离子形成的盐是不稳定的，如氯酸羟胺自发分解为硝酸羟胺和二氧化氯。^[5]

其离子在溶液中可以和氧化性离子发生反应：

NH₃OH⁺ + 2 HSO₅⁻ → 2 SO₄²⁻ + N₂ + 3 H₂O + 3 H⁺^[6]

2 NH₃OH⁺ + 2 Fe^III → 2 Fe^II + N₂ + 2 H₂O + 4 H⁺^[7]
