Abstract

Sorbic acid reacts with nitrite to yield mutagenic products such as 1, 4-dinitro-2- methylpyrrole (NMP) and ethylnitrolic acid (ENA). In order to know the stability of these compounds, a kinetic study of their decomposition reactions was performed in the 6.0− 9.5 pH range. The conclusions drawn are as follows:(i) The decomposition of NMP occurs through a nucleophilic attack by OH− ions, with the rate equation as follows: r= k decNMP [ ...
