Fig. 3. Plot of the rate constant kg vs. AI for the electron transfer of Eq. (6). The scavengers used are named in the figure. Abbreviations mean BP — benzophenone, NA — naphthaline, TEA — triethylamine, TMPD — dimethyl-p-phenylene-di-amine. [From Ref 11, with permission of the editors.]...

The important tri-amino azo compound is the one in which two amino groups are in one ring, ortho and para to the azo group and one amino group meta to the azo group in the other ring. The constitution of the compound is proven by its preparation from meta-phenylene di-amine, we/a-di-amino benzene. This is diazotized so that only one... 

Thiourea derivatives 164 were prepared by Kaupp et al. by mechanochemical reactions in which stoichiometric quantities of solid o-phenylene-di-isothiocyanate 161 reacts with the solid aromatic amines 162 in a ball-mill at room tanperature (Retsch MM2(X)0 miU with a lOmL stainless steel beaker and balls) [31]. The products, l-(aminoaryl-thiocarbonyl)-benzimidazolidine-2-thiones 163 were presumably...

Other antioxidant. For example, in the case of PE, 3% by weight of carbon black is more efficient than 2,6-di-fgrt-butyl-4-methylphenol at 140°C [1]. However, the use of carbon blacks is very complicated and care must be taken against their antagonistic effect, which appears when they are combined with other antioxidants such as certain phenols or amines (diphenyl p-phenylene-diamine). 

Solvent extraction gas chromatographic methods have been described for determining alkylated cresols (2,6-di-tert-butyl-p-cresol) and amine antioxidants (N-phenyl-2-naphthylamine, p-phenylene diamine type) and Santoflex (NN sec-heptyl phenyl-p-phenylene diamine) in polybutadiene. 

The principal groups lead to the endings -diacetic acid and -di(ethylamine) , respectively, in these two cases. The central unit —Y— is cited as the bivalent radical, p-phenylene- for -C6H4- and oxy- for O. Locants are added and the full names become p-phenylenediacetic acid and 2,2 -oxydi(ethyl-amine). The parentheses in the latter name serve te remove possible confusion with a derivative of diethylamine.
