Interaction of Chlorine and Organic Molecules -Effects of Inorganics.

摘要

The effect of heavy metal ions,particularly ferric and manganese ions,on reactions of organic molecules and chlorine in aqueous media,were studied. The conversion of amino acids (phenylalanine) to the corresponding aldehydes and nitriles by chlorine treatment was remarkably enhanced in the presence of ferric ion. In particular the enhancement was more evident with the nitrile compound production. The result implies that both the rates and courses of reactions between organics and chlorine (hypochlorite) can be altered greatly in the water containing a high concentration of ferric ion. Also it implies a rapid depreciation of active chlorine in such water. No catalyzing effect was observed with manganese ion. Amino acids are known to interact with active chlorine in water to form such potentially hazardous compounds as aldehydes,nitriles and their chlorinated derivatives. However,in naturally existing conditions,the problem is compounded by a number of other factors. One of these was assumed to be heavy ions which are often abundant in water systems,especially those in Rhode Island.
