“…The destruction of one of the rings leads to phthalic anhydride or its substituted analogues. More than 60 products of 2-methylnaphthalene chlorination were detected in the reactions with different doses of chlorine water [ 99 ].…”

“…The aqueous chlorination reaction of α-naphthol is very fast, but it mainly affects only the activated phenol nucleus [ 99 ]. The corresponding chain of transformations based on substitution, addition, and hydrolysis reactions leads to its complete destruction with the formation of phthalic anhydride, benzoic acid, and ortho -chlorobenzoic acid.…”

The purity of drinking water is an important issue of the human life quality. Water disinfection has saved millions people from the diseases spread with water. However, that procedure has a certain drawback due to formation of toxic organic disinfection products. Establishing the structures of these products and the mechanisms of their formation and diminishing their levels in drinking water represent an important task for chemistry and medicine, while mass spectrometry is the most efficient tool for the corresponding studies. The current review throws light upon natural and anthropogenic sources of the formation of disinfection by-products (DBPs) and the mechanisms of their formation related to the structural peculiarities and the presence of functional groups. In addition to chlorination, bromination is discussed since it is used quite often as an alternative method of disinfection, particularly, for the purification of swimming pool water. The benefits of the contemporary GC/MS and LC/MS methods for the elucidation of DBP structures and study of the mechanisms of their formation are discussed. The reactions characteristic for various functional groups and directions of transformation of certain classes of organic compounds in conditions of aqueous chlorination/bromination are also covered in the review.

“…The mech anisms of the transformation of humic and fulvic acids under the conditions of water chlorination were studied using various model organic substrates. Such studies are usually accompanied by drafting detailed diagrams of their transformations [9][10][11][12][13][14]. Similar studies were also conducted directly with anthropo genic ecotoxicants [15].…”

The possibility of the formation of toxic products at the stage of drinking water disinfection as a result of interaction of disinfectants, such as chlorine and sodium hypochlorite, with model organic com pounds, structural fragments of natural humic substances is investigated using gas chromatography-mass spectrometry (GC-MS). Both qualitative and quantitative analysis of the products of water chlorination of dibenzoylmethane and cinnamic acid by chlorine and sodium hypochlorite was performed under the condi tions of an equimolar amount and five and fiftyfold excess of the chlorinating agent. Detailed diagrams of the transformation of organic compounds under the conditions simulating the process of natural water dis infection are drawn. The studies indicate that the use of chlorine leads to a greater variety and higher concen trations of chlorinated products compared to sodium hypochlorite.
