The chemical reactions between nitrogen dioxide vapour and diphenylamine (DPA), some of its nitro/nitroso derivatives and between their consecutive products have been studied at temperatures of about 23 °C, whereby cellulose was used as substrate material. The following stabilizer compounds were used as starting components: DPA, N-NO-DPA, 2-NO2<>-DPA and 4-NO2-DPA. Concentration profiles as function of added nitrogen dioxide have been measured by HPLC. These profiles are similar to the ones obtained by accelerated aging, and the typical consecutive stabilizer products have been formed. The profiles are interpreted in terms of possible reactions. Furthermore, the influences of time and light on the decomposition of the mono-nitro-N-nitroso compounds have been investigated. The consequences of these reactions are discussed to explain differences between the storage aging at ambient temperatures and the higher temperature induced accelerated aging. The reactivity towards nitrogen dioxide for each stabilizer compound was obtained by a kinetic model for the decrease of the starting component.(Author abstract)
