용도
용도
2-Naphthylamine was widely used in themanufacture of dyes and in rubber. Currently, its use is curtailed because of thehealth hazard.
일반 설명
A white to reddish colored solid in the form of flakes. Slightly soluble in hot water and denser than water. Toxic by ingestion, inhalation and skin absorption. Used to make dyes and agricultural chemicals.
제조 및 합성 방법
생산 방법
2-Naphthylamine was previously produced in substantial amounts for nearly 50 years but is no longer produced commercially. It is now used exclusively for research, and only rarely. It was formerly used in the manufacture of dyestuffs and as an antioxidant in the rubber industry. Prior to termination of its domestic production and use in the dye and rubber industries, an estimated 1000 U.S. workers were possibly exposed to 2-naphthylamine by inhalation and dermal routes. Currently, laboratory technicians and scientists who use the compound for research purposes may constitute the group with the greatest risk of potential exposure.
