On January 31, 2007, Hua, Guoxiong; Zhang, Qingzhi; McManus, Derek; Slawin, Alexandra M. Z.; Woollins, J. Derek published an article.SDS of cas: 4719-04-4 The title of the article was Improvement of the Fe-NTA sulfur recovery system by the addition of a hydroxyl radical scavenger. And the article contained the following:
The degradation of nitrilotriacetic acid (NTA), which results from the oxidation of hydroxyl radicals formed in the process, is a major deficiency in the present Fe-NTA system for the oxidation of hydrogen sulfide to sulfur by air. The degradation of NTA can be slowed down considerably by the addition of a hydroxyl radical scavenger. In this study, a series of inorganic and organic materials was tested as scavengers / inhibitors of hydroxyl radicals in attempts to improve the Fe-NTA system. The results showed that N-methylpyrrolidinone and ethylene glycol could be used as potentially powerful scavengers of hydroxyl radicals to improve the Fe-NTA system. The experimental process involved the reaction of 2,2′,2”-(1,3,5-Triazinane-1,3,5-triyl)triethanol(cas: 4719-04-4).SDS of cas: 4719-04-4
