The reaction of the herbicide prometryne (CgH16N5-S-CH3) with sodium hypochlorite has been investigated from the kinetic and mechanistic stand point. Under the fixed experimental conditions: pH= 7, T= 25" C,[NaClO]/[substrate]= M)/(10-5 M), prometryne oxidation takes place according to the following pathway: RS-CH3 (P)-R-SO-CH3 (a)-R-SO2-CH3 (b)-RO- SOZ-CH~(x)-R-OH (c), where R stands for C~ HI~ N~, Le., the substituted triazine ring of ...
