Nitrobenzene is an organic compound, also known as spot oil and bitter almond oil. It is a colorless or yellowish oily liquid with bitter almond flavor. Insoluble in water, the density is higher than that of water; Soluble in ethanol, ether, benzene and oil. It will burn and explode in case of open fire and high heat. React violently with nitric acid.

Nitrobenzene is obtained by nitrating benzene with nitric acid and sulfuric acid. As an intermediate in organic synthesis and a raw material for producing aniline. It is used in organic synthesis industry, such as the production of dyes, spices and explosives.

chemical property

It is very active in chemistry and can be reduced to diazonium salt, azobenzene and so on. It will burn and explode in case of open fire and high heat. React violently with nitric acid. It is obtained by nitrating benzene with nitric acid and sulfuric acid. As an intermediate in organic synthesis and a raw material for producing aniline. Nitrobenzene must undergo electrophilic substitution under strong conditions to produce meta-products; It has weak oxidation and can be used as an oxidant for oxidative dehydrogenation. Nitrobenzene is usually prepared by the reaction of mixed acid of nitric acid and sulfuric acid with benzene.
