Nitrobenzene Chemical Properties,Uses,Production


Nitrobenzene (chemical formula: C6H4NO2) is a yellowish, oily, aromatic nitro-compound. The most important application of nitrobenzene (consuming 95%) is for the manufacturing of aniline, which is an important industrial precursor. Besides aniline, it can also be used to generate related derivatives such as azobenzene, nitrosobenzene and phenylhydroxylamine. Moreover, it can be used for the production of lubricating oils, dyes, drugs, pesticides, and synthetic rubber. Another special application of it is masking unpleasant odors emitting from shoe, floor polisher, and leather as well as paint solvents. In addition, it can sometime used as a solvent, especially for electrophilic reagents in the laboratory. The nitrobenzene is mainly manufactured through the nitration of benzene with the mixture of concentrated sulfuric acid, water and nitric acid. However, the reaction process is quite dangerous due to the exothermicity of the reaction.


Chemical Properties

Nitrobenzene is a pale yellow to dark brown oily liquid whose odor resembles bitter almonds (or black paste shoe polish).

Chemical Properties

yellow liquid


Nitrobenzene is an organic compound used a standard for detection and analyses as well as its removal from the environment. The compound’s cytotoxic effects have been studied in a hepatocarcinoma cell line.


The primary use of nitrobenzene is in the captive production of aniline, with about 97.5% of nitrobenzene production consumed in this process. The major use of aniline is in the manufacture of polyurethanes. Nitrobenzene is also used as a solvent in petroleum refining, in the manufacture of cellulose ethers and acetate, and in Friedel-Crafts reactions to hold the catalyst in solution. It is also used in the synthesis of other organic compounds including acetaminophen, which is an over-the-counter analgesic commonly known as Tylenol?.
Nitrobenzene is used as a flavoring agent, a perfume for soaps and as a solvent for shoe dyes.


For the manufacture of aniline; in soaps, shoe polishes; for refining lubricating oils; manufacture of pyroxylin Compounds.


ChEBI: A nitroarene consisting of benzene carrying a single nitro substituent. An industrial chemical used widely in the production of aniline.


Nitrobenzene is produced commercially by the exothermic nitration of benzene with fuming nitric acid in the presence of a sulfuric acid catalyst at 50 to 65℃. The crude nitrobenzene is passed through washer-separators to remove residual acid and is then distilled to remove benzene and water.

General Description

A pale yellow to dark brown liquid. Flash point 190°F. Very slightly soluble in water. Toxic by inhalation and by skin absorption. Combustion give toxic oxides of nitrogen. Density 10.0 lb /gal.

Air & Water Reactions

Very slightly soluble in water.

Reactivity Profile

Aluminum chloride added to Nitrobenzene containing about 5% phenol caused a violent explosion [Chem. Eng. News 31:4915. 1953]. Heating a mixture of Nitrobenzene, flake sodium hydroxide and a little water led to an explosion, discussed in [Bretherick's 5th ed. 1995]. Mixed with oxidants, i.e. dinitrogen tetraoxide, fluorodinitromethane, nitric acid, peroxodisulfuric acid, sodium chlorate, tetranitromethane, uranium perchlorate, etc., forms highly sensitive explosive, [Bretherick 5th ed, 1995]. Heated mixtures of Nitrobenzene and tin(IV) chloride produce exothermic decomposition with gas production [Bretherick, 5th Ed., 1995].


Toxic by ingestion, inhalation, and skin absorption. Methemoglobinemia. Possible carcinogen.

Health Hazard

Can cause death due to respiratory failure. Classified as extremely toxic. The mean lethal oral dose is probably between 1 and 5 grams. Systemic effects may be delayed for a few hours. Nitrobenzene is rapidly absorbed through the skin. It is a powerful methemoglobin former. Ethyl alcohol aggravates intoxication caused by Nitrobenzene exposure.

Fire Hazard

Moderate explosion hazard when exposed to heat or flame. Reacts violently with nitric acid, aluminum trichloride plus phenol, aniline plus glycerine, silver perchlorate and nitrogen tetroxide. Avoid aluminum trichloride; aniline; gycerol; sulfuric acid; oxidants; phosphorus pentachloride; potassium; potassium hydroxide. Avoid sunlight, physical damage to container, freezing, and intense heat.

Safety Profile

Confirmed carcinogen. Human poison by an unspecified route. Poison experimentally by subcutaneous and intravenous routes. Moderately toxic by ingestion, skin contact, and intraperitoneal routes. Human systemic effects by ingestion: general anesthetic, respiratory stimulation, and vascular changes. An experimental teratogen. Experimental reproductive effects. Mutation data reported. An eye and skin irritant. Can cause cyanosis due to formation of methemoglobin. It is absorbed rapidly through the skin. The vapors are hazardous. to heat and flame. Moderate explosion hazard when exposed to heat or flame. Explosive reaction with solid or concentrated alkali + heat (e.g., sodium hydroxide or potassium hydroxide), aluminum chloride + phenol (at 12O°C), aniline + glycerol + sulfuric acid, nitric + sulfuric acid + heat. Forms explosive mixtures with aluminum chloride, oxidants (e.g., fluorodinitromethane, uranium perchlorate, tetranitromethane, sodium chlorate, nitric acid, nitric acid + water, peroxodsulfuric acid, dinitrogen tetraoxide), phosphorus pentachloride, potassium, sulfuric acid. Reacts violently with aniline + glycerin, N20, AgCLO4. To fight fne, use water, foam, CO2, dry chemical. Incompatible with potassium hydroxide. When heated to decomposition it emits toxic fumes of NOx. See also NITRO COMPOUNDS OF AROMATIC HYDROCARBONS.

Potential Exposure

Nitrobenzene is used in the manufacture of explosives and aniline dyes and as solvent and intermediate. It is also used in floor polishes; leather dressings and polished; and paint solvents, and to mask other unpleasant odors. Substitution reactions with nitrobenzene are used to form m-derivatives. Pregnant women may be especially at risk with respect to nitrobenzene as with many other chemical compounds, due to transplacental passage of the agent. Individuals with glucose-6-phosphate dehydrogenase deficiency may also be special risk groups. Additionally, because alcohol ingestion or chronic alcoholism can lower the lethal or toxic dose of nitrobenzene, individuals consuming alcoholic beverages may be at risk.

First aid

If this chemical gets into the eyes, remove any contact lenses at once and irrigate immediately for at least 15 minutes, occasionally lifting upper and lower lids. Seek medical attention immediately. If this chemical contacts the skin, remove contaminated clothing and wash immediately with soap and water. Seek medical attention immediately. If this chemical has been inhaled, remove from exposure, begin rescue breathing (using universal precautions, including resuscitation mask) if breathing has stopped and CPR if heart action has stopped. Transfer promptly to a medical facility. When this chemical has been swallowed, get medical attention. Give large quantities of water and induce vomiting. Do not make an unconscious person vomit.

Purification Methods

Common impurities include nitrotoluene, dinitrothiophene, dinitrobenzene and aniline. Most impurities can be removed by steam distillation in the presence of dilute H2SO4, followed by drying with CaCl2, and shaking with, then distilling at low pressure from BaO, P2O5, AlCl3 or activated alumina. It can also be purified by fractional crystallisation from absolute EtOH (by refrigeration). Another purification process includes extraction with aqueous 2M NaOH, then water, dilute HCl, and water, followed by drying (CaCl2, MgSO4 or CaSO4) and fractional distillation under reduced pressure. The pure material is stored in a brown bottle, in contact with silica gel or CaH2. It is very hygroscopic. [Beilstein 5 H 233, 5 I 124, 5 II 171, 5 III 591, 5 IV 708.]


Concentrated nitric acid, nitrogen tetroxide; caustics; phosphorus pentachloride; chemically-active metals, such as tin or zinc. Violent reaction with strong oxidizers and reducing agents. Attacks many plastics. Forms thermally unstable compounds with many organic and inorganic compounds.
