Chemical changes of organic compounds in chlorinated water. XIII: Gas chromatographic−mass spectrometric studies of the reactions of irgasan DP 300 [5-chloro-2-(2,4-dichlorophenoxy)phenol] with chlorine in dilute aqueous solution

摘要: Abstract The reactions of Irgasan DP 300 with chlorine in water were investigated by means gas chromatography (GC) and GC—mass spectrometry. was shown to produce dichloro- trichloro-2-(2,4-dichlorophenoxyl)phenols chlorine-treated water, followed the decomposition these intermediates chlorophenols. No polychlorinated dibenzo- p -dioxins detected solutions. production some compounds is dependent on number equivalents per mol reaction pH.
