Abstract
The reaction of 2,4-dinitrobenzaldehyde with hydroxide ion in water is first order in the substrate. The reaction order in hydroxide ion var ies from one to two at lower and higher OH- concentrations, respective ly. The reaction mechanism has been suggested, the pK(a) value of reac tion product 2-nitro-4-nitrosophenol and the equilibrium constant of f ormation of the Meisenheimer adduct from 2-nitro-4-nitrosophenoxide an d hydroxide ion have been determined.
