Chemical properties

It has active chemical properties and can be reduced to diazonium salts, azobenzene, etc. It will burn and explode when exposed to open flames and high heat. It reacts violently with nitric acid. It is obtained by nitrating benzene with a mixture of nitric acid and sulfuric acid. It is used as an intermediate in organic synthesis and as a raw material for the production of aniline. Nitrobenzene must undergo electrophilic substitution reactions under relatively strong conditions to generate meta-products; it has a weak oxidizing effect and can be used as an oxidant for oxidative dehydrogenation. Nitrobenzene is often produced by reacting benzene with a mixed acid of nitric acid and sulfuric acid. It is mainly used to produce aniline, benzidine, azobenzene, etc. Nitrobenzene is highly toxic. Inhaling a large amount of vapor or contaminating the skin can cause acute poisoning, oxidizing or complexing hemoglobin, turning the blood into dark brown, and causing headaches, nausea, vomiting, etc.

Production and uses

Nitrobenzene is produced from benzene on a large scale.

It’s used to make aniline, which is then used to make dyes, drugs, pesticides, and synthetic rubber.

It’s also used to make lubricating oils.

Health effects Nitrobenzene is toxic by inhalation and skin absorption, It can cause cancer, It can cause male reproductive toxicity, and It can cause skin burns.
