APPLICATIONS
|
| Naphthylamine is an aromatic amine which can be obtained from nitronaphthalene
(with iron and hydrochloric acid) or naphthol with sodium acetate, ammonium
chloride. There are position isomers; 1-naphthylamine and 2-naphthylamine.
2-Naphthylamine
was used as an Intermediate for wide application target molecules including
dyestuffs, agrochemicals, and antioxidants. But its use is restricted or
prohibited due to cancer suspect. Naphthylamine is the naphthalene homologues of aniline. Naphthylamine is the
starting material in the dye manufacturing and rubber industry. Numerous sulfo- and nitro-group substituted
naphthylamine on the ring system offer important roles to each characteristic
colours directly and in preparing next target colorants. Phenyl group
substituted naphthylamines are naphthalene homologues of phenylenediamines used
as parent compounds in vulcanization accelerators and in antioxidants for rubber
industry. Naphthylamine can be oxidized by chromic acid into naphthoquinone
which is the fundamental ring structure related with vitamin K.
Tetrahydronaphthylamine can be oxidized by potassium permanganate into adipic
acid. Naphthyl structure is found as a ligand in transition-metal catalyts
particularly in the form of bi-naphthyl which is composed of two naphthyl rings
connected at one carbon site on each ring.
N-Phenyl-1-naphthylamine
is a lipophilic white to slight brownish
crystalline powder that is used as an antioxidant
in various in rubbers and lubrication oils.
It is also used as an itermediate for vulcanization
accelerators, dyes and other organic chemicals.
