The electronic spectra of the copolymers poly(aniline-co-p-nitroaniline) and poly(aniline-co-o-nitroaniline) show hypsochromic shift. The shift has been observed in the bands corresponding to π → π transition as well as in the exciton transition. The presence of nitro-group not only ...

In such compositions, the dinitroaniline compound can be present in a concentration from about 2 to 98% by weight. In the preparation of dust compositions, the dinitroanilines can be compounded with any of the finely divided solids such as pyrophyllite, talc, chalk, gypsum and the like. ...

3) P-nitroaniline 对-硝基苯胺 1. Both steady-state and transient radiolysis experiments were performed to gain insight into the kinetics and mechanisms of radiation induced degradation of p-nitroaniline (p-NA) in aqueous solutions. 本文利用60CoY射线稳态辐照对-硝基苯胺水溶液,研究其降解行为。
Although amino group is o- and p-directing in aromatic electrophilic substitution reactions, aniline on nitration gives a substantial amount of mnitroaniline. Give reason. View Solution pKbof aniline is more than that of methylamine. Why?
