2-NAPHTHYLAMINE 1. Exposure Data. 2-NA has been detected in rubber antioxidants such as Nonox S and Agerite Resin at levels of 0.25% [2500 ppm] (Veys, 2004). N-phenyl-2-naphthylamine, also a rubber antioxidant, can be contaminated with 2-NA, and can also be metabolized (dephenylated) into 2-NA to some extent.

- What is N-phenyl-1-naphthylamine (P 1na)?
- N-Phenyl-1-naphthylamine (P 1NA) serves as anantioxidant in various lubrication oils and also as a protective agent in rubbers as well as rubber mixtures. (Koennecker et al., 1998 ). It was estimated that the annual production of P 1 NA was 5800–6300 tons from 1986 to 1990 in the world ( Koennecker et al., 1998 ).
- What are the future trends of rubber antioxidants?
- The perspectives on the future trends of rubber antioxidants have been presented. Elastomers, especially diene-rubbers containing unsaturated double carbon bonds in the main chains, are vulnerable to thermal/oxygen aging, which would make the elastomers less elastic and result in earlier failure of the elastomer products.
- Why do we need antioxidants for rubber composites?
- Therefore, for a real application, the antioxidants are indispensable to retard the thermal-oxidative-aging process of the rubber composites and then prolong the service life. In this review, we systematically review the recent progress of antioxidants for rubber.
- How can Antioxidants improve the antioxidative capacity of the rubber matrix?
- Generally speaking, as shown in Figs. 2 and 3, there are two main strategies to improve the antioxidant's antioxidative capability for the rubber matrix: (i) using two or more antioxidants together, and (ii) molecular design of antioxidants. Fig. 2.
- Can rubber antioxidants contain rare-earth ions?
- The recently reported rubber antioxidants containing rare-earth ions are summarized in Fig. 4, for instance, Sun et al. prepared a novel hindered phenol rare-earth complex (DTSm) (Fig. 4f) by a simple and green method using 3,5-di-tert-butyl-4-hydroxybenzoic acid (DT) and samarium chloride hexahydrate (SmCl3 ·6H 2 O) via coordination reaction.
- Which antioxidants are used in rubber vulcanization?
- The amine and phenolic antioxidants are the most widely used rubber antioxidants (Fig. 1b and c). Generally, the phenolic antioxidants have poor antioxidative efficiency (compared to amine antioxidants) and they can delay vulcanization, but they cause little discoloration problems.
