Corrosive properties of ammonia and liquid ammonia
Thread Content
I would like to ask everyone, which one is more corrosive, ammonia or liquid ammonia? Does ammonia or liquid ammonia refer to something that is corrosive to copper? Which friend has the national standard for liquid ammonia? Please share it; thanks!
The poster is referring to liquid ammonia and ammonia water, right? Safety Data Sheet: Liquid ammonia: This substance poses serious hazards to the environment; special attention must be paid to preventing contamination of surface water, soil, the atmosphere, and drinking water. http://www.anquan.com.cn/msds/tail.asp?id=28 Ammonia: Due to its alkaline nature, this substance is harmful to the environment; special attention should be paid to fish and mammals. http://www.anquan.com.cn/msds/tail.asp?id=801 Liquid ammonia is not corrosive to most substances, but it is corrosive to metals such as copper and silver in the presence of water vapor. GB 536-1988 Liquid anhydrous ammonia http://bbs.hcbbs.com/thread-16984-1-9.html Last edited by zhangyong6404 on 2009-3-22 00:08]
