Notes:
The reversible interaction of N-(1-ethylpropyl)-3, 4-dimethyl-2, 6-dinitroaniline (1) with HO- is characterized by several kinetic processes. The relaxation times of two of them were measured. It is suggested that the faster one is related to the protonation-deprotonation of the 3-methyl group and the value of the protonation rate is 0.19 s-1. The slowest process leads to the dianionic species with maximum absorption at 340 nm where one HO- group adds to the unsubstituted ring position of an anion derived from 1 by deprotonation of either the NH or the 3-methyl group. The rate and equilibrium constants for the formation of this species are reported.
