Nitrobenzene or mononitrobenzene is an organic compound with the formula C6H5NO2.
Nitrobenzene can be reduced to aniline.
Nitrobenzene is a yellowish liquid, with a smell reminiscent of almonds.
Nitrobenzene used to be more available in the past, but in recent years it has been phased out from many places due to it's high toxicity and it's difficult to acquire.
Nitrobenzene is prepared by nitration of benzene, using a mixture of concentrated sulfuric acid and nitric acid, also known as nitrating mixture. Water is used as solvent. The production of nitrobenzene is one of the most dangerous processes conducted in the chemistry because of the exothermicity of the reaction (ΔH = −117 kJ/mol).
- Make trinitrobenzene
- Make aniline
- Make paracetamol
Nitrobenzene is very toxic. Proper protection should be worn when working with the compound.
Nitrobenzene should be kept in closed glass bottles, marked with a clear label and hazard symbols, in a hazardous chemical locker.
Burning it releases lots of soot and unburnt benzene derivatives.
