Abstract

Environmental fate of aromatic sulfonates is relatively unknown. Thisstudy reports the findings of wet air oxidation (WAO) of several sulfonic compounds, specifically 5-nitro-o-toluenesulfonic acid (NTSA). WAO is effective in the oxidation of NTSA, a compound similar in structure to dinitrotoluenesulfonates which are major components of TNT red water. The WAO reaction is first-order with respect to NTSA; the order with respect to oxygen pressure is 0.6. The activation energy is approximately 21 kcal/mol. The reaction rate is significantly enhanced withthe addition of 5 mg/L Cu(II) catalyst. The effect of initial pH on rate of NTSA oxidation is complex. Higher reaction rates are observed both at low and high pH's, with a better overall rate being achieved atlow pH. Some properties of NTSA (e.g., UV, IR, and NMR) were obtainedto provide additional information.
