The stuff from User:18.104.22.168 was appears to be a paste of substantial parts of the text from http://www.gasdetection.com/TECH/hcn.html - I have removed this text. I did not restore the line about cyanogen being found in nature AFAIK it is not in the sense meant (although cyanide salts are). CustardJack 11:32, 12 May 2005 (UTC)
In other sources, the boiling point is −20.7°C. Andres 03:11, 13 May 2006 (UTC)
Also interesting to note is the fact that cyanogen burns with a non-luminous flame with a flame temperature that approaches the temp of the surface of the sun.

Discovery of cyanogen
The first person to synthesize cyanogen was Gay-Lussac in 1815. He also determined its empirical formula and named it. Scheele and Berthollet might have unwittingly synthesized cyanogen during their research, but they did not claim to have discovered or characterized it, and they did not contest Gay-Lussac's claim. Therefore I altered the article's "History" section to conform to these facts.Cwkmail (talk) 10:39, 26 May 2010 (UTC)
