Analysis of an important pharmaceutical reactant 2,4-dinitrophenylhydrazine. Part 2. A kinetic method for specific determination
Abstract
A new specific method for the kinetic analysis of 2,4-dinitrophenylhydrazine in its reaction with aliphatic amines followed by alkali hydroxide in dimethyl sulfoxide is described. This method is superior to other colorimetric methods for polynitroaromatics where unstable colours and a lack of specificity preclude their efficacy.
