Description
A pale yellow, viscous liquid formed by the reaction of fuming Nitric acid on Benzene. Nitrobenzene was discovered by Mitscherlich in 1834. When cooled, it forms bright yellow crystals. Nitrobenzene is very toxic. It is used in the manufacture of aniline dyes. as well as being an ingredient in soaps, polishes (metal and shoe), and lubricating oils.
