Irradiation behavior of some N,N-disubstituted p-phenylenediamines: Irradiation behavior of some N,N-disubstituted p-phenylenediamines.Several substances are used for example 74-31-7 and 27417-40-9 which are their cas registry numbers. Giurginca, Maria; Tavaru, Erika (Inst. Cercet. Prelucrare Cauciuc Mase Plast., Bucharest, Rom.). Ind. Usoara, 30(5), 211-15 (Romanian) 1983. CODEN: INUSAT. ISSN: 0019-7785. DOCUMENT TYPE: Journal CA Section: 39 (Synthetic Elastomers and Natural Rubber) Section cross-reference(s): 22, 74 Spectral data indicated that the UV-, IR-, and visible light-induced acceleration of the autoxidn. of 5 N,N'-disubstituted p-phenylenediamines (rubber antioxidants) to semiquinones and quinonediimines dependent on the substituents. The kinetics of the reaction indicated a complex mechanism, implying successive reactions of the order 1 and 0, based on the diamines, which confirmed a presumption of a 2-step process (1st step being oxidn. and the 2nd step being autocatalytic). .
