Sep 13, 2017 · The HCNCO complex and its X-ray induced transformation to HNCCO in solid noble gas (Ng) matrices (Ng = Ne, Ar, Kr, Xe) was first characterized by matrix isolation FTIR spectroscopy at 5 K. The HCNCO complex was obtained by deposition of HCN/CO/Ng gaseous mixtures. The assignment was based on extensi …

急性氰化氢中毒的临床表现为患者呼出气中有明显的苦杏仁味，轻度中毒主要表现为胸闷、心悸、心率加快、头痛、恶心、呕吐、视物模糊。 重度中毒主要表现呈深昏迷状态，呼吸浅快，阵发性抽搐，甚至强直性痉挛。 二次世界大战中纳粹德国常把氰化氢作为毒气室的杀人毒气使用。 溶解性：与 乙醇 、 乙醚 、 甘油 、 氨 、 苯 、 氯仿 和水等混溶。 弱酸，与碱作用生成盐，其水溶液沸腾时，部分水解而生成 甲酸铵。 在碱性条件下，与 醛 、 酮 化合生成氰醇，与 丙酮 作用生 …

Feb 1, 1984 · Radiofrequency and microwave rotational spectra of the complexes HCN CO 2 and DCN CO 2 have been obtained using molecular beam electric resonance spectroscopy. The spectra are characteristic of prolate asymmetric rotors.

The HCNCO complex and its X-ray induced transformation to HNCCO in solid noble gas (Ng) matrices (Ng = Ne, Ar, Kr, Xe) was first characterized by matrix isolation FTIR spectroscopy at 5 K. The HCNCO complex was obtained by deposition of HCN/CO/Ng gaseous mixtures.

Dec 5, 2016 · TL;DR: The HCNCO complex and its X-ray induced transformation to HNCCO in solid noble gas (Ng) matrices was characterized by matrix isolation FTIR spectroscopy and it was found that the formation of complexes with CO had a remarkable effect on the radiation-induced transformations of HCN.

工业生产HCN是利用甲烷和氨混合气催化反应制得，该反应是强烈的放热反应。 氨与 CO 在催化剂（例如Al2O3或CeO2）表面在770-970K反应也产生HCN。 但由H2，N2和C直接化合生成HCN，只能在高于2070K时发生。 [2] “科普中国”是为我国科普信息化建设塑造的全... 氢氰酸（Hydrocyanic acid），是氰化氢的水溶液，是一种极弱的酸，易挥发。
