- 概述:硫氰酸钾,分子式为KSCN,又称硫氰化钾,英文Potassium Thiocyanate,为无色单斜晶系结晶。相对密度1.886。熔点约172.3℃。易溶于水并 因大量吸热而降温,也溶于酒精(乙醇)和丙酮。在低温下可得半水物结晶(KSCN.0.5H2O),-29-6.8℃时稳定,灼热至430左右变蓝,但冷后又重 新变为无色。加热至500时分解。它遇Fe3+(铁盐)生成血红色的硫氰酸铁络离子FeSCN2+(硫氰化铁),是检验 Fe3+ 离子十分灵敏的方法,可以 排除目前已知的一切其它金属离子的影响。与亚铁盐不反应。易潮解,应密封保存。有低毒。但氰酸钾是剧毒物质,目前国家已经限制生产。
