FORMATION OF DIHALOACETONITRILES BY CHLORINATION OF NATURAL WATER

Date Issued:
1980
Summary:
Dihaloacetonitriles (DHANs) are shown to be produced by the chlorination of natural water, thus joining the ranks of the trihalomethanes (THMs) likewise produced by chlorination. Certain amino acids such as aspartic acid, tryptophan, and tyrosine are implicated as precursor substances for the DHANs and also to some extent for the THMs. The degradation of DHANs by hydrolysis and by thiosulfate was studied. Various methods of analysis are evaluated with respect to their ability to determine DHANs and THMs. The dilemma faced by water plants in dealing with the dual problem of DHANs and THMs is discussed. The role of hydrolysis in the formation of THMs has also been evaluated.
