氰化钡barium cyanide),化学式 Ba(CN)2,分子量为189.38,白色光亮鳞状结晶。不溶于水,微溶于乙醇,遇酸或露置空气中能吸收水分和二氧化碳分解出剧毒的氰化氢气体。[2]

制备

[编辑]

它是由氢氰酸氢氧化钡在水中或是石油醚中反应而成的。[3][4]

它也可以由氢氧化钡空气氮气中燃烧而成。[4]

性质

[编辑]

氰化钡是一种吸湿性固体,会水合成二水合物 Ba(CN)2 · 2 H2O ,为棱柱结构。它在 100 °C 时会放出结晶水[4] 当 Ba(CN)2 在水蒸气中加热时,会形成氢氧化钡 Ba(OH)2 NH3一氧化碳 CO。[4]

它和粉加热反应,形成碳化钡[5]
