HCN is formed by the photolysis of ammonia in the presence of acetylene at room temperature. There is a 70% decrease in the yield of HCN when the temperature is lowered to 178 K and two new reaction products, acetonitrile and acetaldehyde ethylidenehydrazone (6), are formed. Photolysis of 6 yields acetonitrile, and the hydrogen atom initiated decomposition of acetonitrile yields HCN. Aziridine, a predicted
HCN 是在室温下在乙炔存在下通过氨光解形成的。当温度降低到 178 K 时,HCN 的产率下降了 70%,并形成了两种新的反应产物,乙腈和乙醛亚乙基腙(6)。6 的光解产生乙腈,氢原子引发乙腈分解产生 HCN。氮丙啶是一种预测的反应中间体,在 298 或 178 K 下未检测到。也形成了乙炔的低聚物。傅里叶变换红外光谱表明,在乙炔存在下氨光解形成的低聚物含有 NH 基团,与乙炔直接光解产生的低聚物不同。这些光化学过程对木星、土卫六、土卫六上 HCN 和发色团形成的可能作用
