补充资料:N-环己基环己胺亚硝酸盐
分子式:C12H23N·HNO2
分子量:228.34
CAS号:3129-91-7

性质:白色结晶。熔点182-183℃(分解)。20℃的蒸气压1.33×10-2Pa。溶解度:水中3.9%,乙醇中9%,甲醇中23%。在碱性介质中稳定,在酸性介质中变为亚硝酸铵。热至175℃时分解并放出氨气。

制备方法:由二环己胺与磷酸反应生成磷酸二环己胺,然后加入亚硝酸钠反应生成亚硝酸二环己胺:反应生成物经洗涤、干燥得成品。

用途:用作气相缓蚀剂。主要用于金属缓蚀保护和阻止金属锈蚀的继续进行。如用于汽车及汽车零件、减速机箱、内燃机、机床工具、刃具量具等,也可用于武器、雷达等设备的金属保护。气相缓蚀剂具有优良的性能,防锈期长,防锈效果好,复杂与简单的部件均适宜。但对黄铜、锡及其合金有腐蚀作用。
