Ozone reaction with 2,4-dinitrotoluene in acetic acid solution

Abstract

2,4-Dinitrotoluene reacts with ozone along two concurrent pathways: at the aromatic ring yielding stable against ozonolysis hydroperoxide, and at the methyl group with retention of the aromatic structure. The relative amount of products undergoing oxidation at the aromatic ring and at the methyl group depends on the ozonation conditions, especially on the process temperature.

“…These problems can be solved by developing new technologies of oxidation of 4-aminotoluene using ozone, which is an affordable and undiluted oxidant [4][5][6]. At present, it is known that in the medium of acetic acid in the presence of cobalt(II) acetate methylarenes with high selectivity are oxidized with ozone to the corresponding aromatic carboxylic acids [4,5], the oxidation at the stage of forming corresponding alcohols or aldehydes being impossible to stop. Therefore, the systematic research of ozone reactions with 4-aminotoluene to develop the basis of technological process of manufacturing aromatic products is an actual task.…”
