其他信息

  • 理化性质:化学式CuI。分子量190.45。白色立方晶体或灰白色粉末,有毒。相对密度5.62,熔点605℃,沸点1290℃。对光和空气稳定。碘化亚铜几乎不溶于水和乙醇,溶于液氨、稀盐酸、碘化钾、氰化钾或硫代硫酸钠溶液,能被浓硫酸和浓硝酸分解。向硫酸铜的酸性溶液中加入过量的碘化钾或在搅拌下,将碘化钾与硫代硫酸钠的混合溶液滴加到硫酸铜溶液中,析出沉淀即得碘化亚铜。除用作试剂等一般用途外,碘化亚铜还用作生产通电热敏纸导电层的材料、医药消毒、机械轴承测温剂,也用于汞的微量分析。 毒性:长期反复与身体接触有害,应避免其与身体直接接触。食入对身体极具危害性。
  • 用途二:用作分析试剂
  • 图谱信息:碘化亚铜(7681-65-4)红外图谱(IR1)
  • 用途:1.碘化亚铜的用途很广泛,可用作有机合成催化剂、树脂改性剂、人工降雨剂、阳极射线管覆盖物,以及加碘盐中的碘来源。在1,2-或1,3-二胺配体存在下,碘化亚铜可以催化溴代芳烃、溴代杂环化合物和乙烯基溴转化为相应碘化物的反应。反应一般在二恶烷溶剂中进行,以碘化钠作为碘化试剂。芳香碘化物一般比对应的氯化物和碘化物活泼,因此,碘化亚铜可以催化一系列卤代烃参与的偶联反应,例如Heck反应、Stille反应、Suzuki反应及Ullmann反应。2-溴-1-辛烯-3-醇与1-壬炔在二氯双(三苯基膦)合钯(II)、氯化亚铜和二乙胺存在下,发生偶联反应生成7-亚甲基-8-十六碳-6-醇。 2.用作有机反应催化剂、阳极射线管覆盖物,也用作动物饲料添加剂等,碘化亚铜还可与碘化汞一起用作测量机械轴承温度升高的指示剂。 3.在格氏试剂参与的许多反应中作催化剂,碘化亚铜也用干Wiff重排反应中。
  • 碘化亚铜检测汞试验:工业上汞被广泛应用于各类仪表、制镜及化工和冶金;农业上常用西力生、赛力散、谷仁乐生等有机汞作为种子消毒剂及杀虫剂;医药上用汞制剂及升汞、甘汞、撤利汞等作为消毒、杀菌剂,汞还可以制作治疗用药如利尿剂。 汞及化合物均有毒,如使用不慎而误食会引起中毒。 [原理] 汞经升华后与碘化亚铜作用,生成红色碘化亚铜汞络合物。本法可检出3μg汞。 碘化亚铜检测汞反应方程式:2Cu2I2+HgHgCu2I4+2Cu [试剂] 碘化亚铜棉花:5g硫酸铜,3g无水硫酸亚铁,溶于100mL水中,在搅拌下加入碘化溶液(7g碘化钾溶于50mL水),离心分离出生成的碘化亚铜沉淀,经水洗后,将其搅拌成混浊液,将浸有此混浊液的脱脂棉阴干备用。 [操作] 置雷因希氏法试验的铜片于试管中,用碘化亚铜棉花轻轻盖好管口。将试管底部在直火上加热,如有汞存在,棉花变红。同时作空白对照。 也可取检材的消化液1滴,加在碘化亚铜棉花上,如有汞,则棉花变红。 参考资料:于维森,高汝钦,靳晓梅 主编.常见化学性食物中毒快速处置技术.
