Description
A colorless, oily liquid with a sweet amine-like odor. Aniline was first isolated in 1826 by Unverdorben and made synthetically in 1841 by Fritzsche. It was the base material for many of the early synthetic dyes. As a result, colors produces from coal-tar derivatives are generally called aniline dyes. Aniline darkens to brown on exposure to air and light. Besides the manufacture of dyes, aniline is used as an Accelerator and Antioxidant in rubbers. It is also used to make Polyurethane foams, fungicides, and explosives.
