Adamic, K. published the artcileFormation of radicals in the amine-inhibited decomposition of tert-butyl hydroperoxide, Recommanded Product: Bis(4-nitrophenyl)amine, the publication is Canadian Journal of Chemistry (1969), 47(2), 295-9, database is CAplus.
The radicals formed in the amine-inhibited, ¦Á,¦Á’-azobis(isobutyronitrile)-initiated decomposition of (tert-BuO)2 at 65¡ã were examined by E.S.R. In the absence of amine a strong peroxy radical signal is obtained. Amines with structures that do not correspond to those of conventional antioxidants (i.e. primary and secondary aliphatic amines and tertiary amines) generally have little or no effect on this signal. Nitroxide radicals are generated from secondary aromatic (diaryl and alkaryl) amines. The rate of conversion of these amines to nitroxides reached a maximum of 50-60% of the rate of chain initiation for some diphenylamines. A maximum concentration of nitroxide of about half the initial amine concentration was obtained with 4,4′-dimethyldiphenylamine. N ,N ,N’,N’-Tetramethyl-p-phenylenediamine is very rapidly oxidized by (tert-BuO)2 to give Wurster’s Blue cation and, presumably, a tert-BuO radical. This amine is therefore an initiator of oxidation rather than an inhibitor as has commonly been supposed. Primary aromatic amines do not appear to form simple aryl nitroxides. It is proposed that arylamino radicals are directly oxidized to nitroso compounds by peroxy radicals.
