Oxidative chlorination of aromatic substrates in water Objective: Chlorination is an important reaction of organic chemistry because of wide variety of uses of chloro-substituted organic compounds in fine chemicals and pharmaceutical intermediates. Therefore, large number of . Unfortunately, little is known about the nature of the reactions of chlorine with organic food constituents. This presentation reviews published information concerning the reactions of chlorine gas (Cl2[g]), aqueous chlorine, and ClO2 with model food compounds, the fate of chlorine during the chlorination of specific food products, and the Cited by:

From lists of published rate constants for the direct reactions of aqueous ozone with substrates we can conclude: if, for example, mg/l ozone is present, the following types of compounds react within less than 10 seconds: sulfite, nitrite, olefinic aliphatic hydrocarbons, phenols, polyaromatic hydrocarbons, organic amines and sulfides.. Much slower to react are some Cited by:

Concerns about possible adverse health effects of drinking water disinfection have centered on chemical by-products produced by reactions of chlorine with various organic precursors during water treatment. The presence of certain organic compounds in raw water prior to treatment can be attributed to chemical manufacturing, processing, distribution, uses, or urban and agricultural land runoff.
