4-壬基酚在氯消毒过程中的氧化途径

AQUEOUS CHLORINATION PATHWAYS OF 4-NONYLPHENOL

利用固相萃取 GG MS测定壬基酚 (NP)及其在氯气消毒过程中产生的副产物 .结果表明 ,NP容易和次氯酸发生反应 ,并检出了包括一氯壬基酚 ,二氯壬基酚 ,三氯苯酚在内的 7种副产物 .用量子化学模型探讨了NP和次氯酚的反应机理 ,NP和次氯酸的反应包括了苯环上的氯取代反应及壬基侧链的断裂反应 .

In this study,the pathways and mechanism between 4-nonylphenol and HOCl reaction was characterized by solid phase extraction(SPE)-GC-MS method and quantum chemical modeling analysis.It was found that 4-nonylphenol react with HOCl easily,and the reaction pathways include two chlorine-substitution reaction on benzene ring and nonyl moiety.Seven byproducts inclu- ding 2-chloro -nonylphenol,26-dichloro-4-nonylphenol,246-trichlorophenol were detected.
