TLDR
In this paper, aqueous phenol solutions were treated with hypochlorite at 20°C under various experimental conditions, and changes in the composition of the chlorination products in water were determined by using gas chromatographic (GC) and GC-mass spectrometric analyses of diethyl ether extracts.About:

Products of Aqueous Chlorination of Bisphenol A and Their Estrogenic Activity
TL;DR: The transcriptional activation-induced by products were detected by a yeast two-hybrid system based on the ligand-dependent interaction of two proteins, a human ER and a coactivator, suggesting that the chlorinated BPA solution elicits an ability to mimic the effect of the estrogen hormone.

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
TL;DR: The reactions of Irgasan DP 300 with chlorine in water were investigated by means of gas chromatography (GC) and GC-mass spectrometry to produce dichloro- and trich chloro-2-(2,4-dichlorophenoxy)phenols in chlorine-treated water, followed by the decomposition of these intermediates to chlorophenols.

Chlorination of Phenols Revisited: Unexpected Formation of α,β-Unsaturated C4-Dicarbonyl Ring Cleavage Products.
TL;DR: New insights are provided into the formation of reactive and toxic electrophiles during chlorine disinfection and evidence is provided for the importance of phenoxy radicals produced by one-electron transfer reactions initiated by chlorine in the production of dicarbonyl ring cleavage products.

Chlorine Derivatives of Phenol Causing Taste and Odor
TL;DR: The problem of pollution by phenolics has been extensively studied and is best understood by water scientists as discussed by the authors, however, few points are sufficiently clarified to permit the problem to be set aside.

Further studies on impurities in chlorophenols
Carl-Axel Nilsson,Lars Renberg +1 more
TL;DR: In this article, the main impurities were chlorinated 2-hydroxydiphenyl ethers (predioxins), precursors to chlorinated dibenzo-p-dioxins (isopredioxins).

Chromatographic evidence for the formation of chlorodioxins from chloro-2-phenoxyphenols
TL;DR: In this article, the photochemical and thermochemical decomposition of trichloro-2-phenoxyphenol have been studied and shown to yield 1,2,3,8-tetrachlorodioxin, two trichlo-odioxins, a dichlorodorioxin and a dichodorodibenzofuran.
