The crude product (mp 52 °C) is separated, washed with hot water, and further purified by crystallization or sweating (draining of the lower melting point isomer) to remove 2-nitronaphthalene (3%) and traces of 2, 4-dinitronaphthalene. purified 1-nitronaphthalene was traditionally reduced with iron in boiling dilute hydrochloric acid, but modern plants use hydrogenation with nickel catalyst. The 1-naphthylamine produced is further purified by distillation under vacuum. The content of 2-naphthylamine in the commercial product is specified at less than 10 ppm., Impurities: Most commercial 1-naphthylamine ... contains 4-10% of 2-naphthylamine if synthesized by methods used in previous decades. Modern production methods give rise to a max of 0.5%., U.S. Production: (1978) PROBABLY GREATER THAN 2.27X10+6 G, (1982) PROBABLY GREATER THAN 2.27X10+6 G, (1985) Data not reported, U.S. Imports: (1977) 5.16X10+7 G (PRINCPL CUSTMS DISTS), (1982) 9.91X10+7 G (PRINCPL CUSTMS DISTS), General Manufacturing Information: 1-Naphthalenamine: ACTIVE |
