Chemical Uses

Description:

N-Phenyl-1-naphthylamine has a molecular weight of 219.28 and a refractive index of 1.7020. It is also known as 1-Naphthylamine, N-phenyl-, α-Naphthylphenylamine, Antioxidant PAN, C.I. 44050, N-(1-Naphthyl)aniline, and N-Phenylnaphthalen-1-amine. This compound has strong antioxidant properties and can help prevent substance deterioration due to oxidation.

Chemical Properties:

brown solid

Uses:

N-Phenyl-1-naphthylamine is an effective antioxidant that helps to reduce oxidation of the oil and rubber components. In addition, it helps to protect the lubrication and bearing oils from corrosion, which can cause damage to the gears and parts. It also helps to safeguard rubbers from ozone degradation, which can lead to cracking and other damage.

In the presence of acids, N-Phenyl-1-naphthylamine will neutralize them in an exothermic reaction forming salts plus water. It is also important to note that it is incompatible with isocyanates and halogenated organics and should always be handled cautiously.
