Industrial amines are combined with acids in concentrated forms for various applications. Recently, an explosion occurred when a scientist was screening different acids and selected concentrated nitric acid to mix with an aliphatic amine. This Case Study describes the incident and aftermath, the chemistry behind the incident, and a short review of the hazards of mixing oxidizing acids with amines, with a focus on hypergolic fuels. An SOP with recommended reaction setup is described as well as corrective actions that were identified after a safety review.

从延迟放热分解中吸取的教训——用强氧化性酸中和胺
工业胺与酸以浓缩形式结合用于各种应用。最近，一位科学家在筛选不同的酸并选择浓硝酸与脂肪胺混合时发生了爆炸。本案例研究描述了事件和后果、事件背后的化学反应，并简要回顾了将氧化性酸与胺混合的危害，重点是自燃燃料。描述了具有推荐反应设置的 SOP 以及在安全审查后确定的纠正措施。
