A kinetic study of the oxidation of 2,4-dinitrophenylhydrazine with acidic bromate

Sreekantha Babu Jonnalagadda  and  Gerald K. Muthakia 

Abstract

The kinetics of the reaction of 2,4-dinitrophenylhydrazine with bromate ion in sulphuric acid solution have been studied by spectrophotometric techniques. In the fast initial step, 2,4-dinitrophenylhydrazine (dnph) is oxidised to the diazonium ion (dnp [graphic omitted]2). The reaction is of first-order with respect to dnph, bromate, and H+. The stoicheiometric ratio of dnph to bromate ion is 1 : 1. The intermediate diazonium ion gives the final products, including 1,3-dinitrobenzene, in a slow reaction.
