4-Chloronitrobenzene Chemical Properties,Uses,Production
Physical properties
p-Nitrochlorobenzene is a yellow crystalline solid with a sweet odor.
Chemical Properties
4-Chloronitrobenzene is a light yellow monoclinic prisms crystallizes, which are insoluble in water and very soluble in toluene, ether, acetone, or hot ethanol. It is incompatible with strong oxidizers and alkalis. It is extensively used in different industries as an intermediate in the manufacture of dyes, rubber, and agricultural chemicals.
Uses
4-Nitrochlorobenzene is an important intermediate in the manufacture of azo dyes and sulfide dyes, the drugs finasteride and paracetamol, the pesticide herbicide, etc. It is also the raw material of rubber antioxidant 4010.
Definition
ChEBI: 4-Chloronitrobenzene is a C-nitro compound.
General Description
Light yellow crystalline solid. Density 1.520 g / cm3. Melting point 83°C. Sweet odor. Very toxic by inhalation, ingestion, and skin absorption. p-Chloronitrobenzene is extensively used in different industries as an intermediate in the manufacture of dyes, rubber, and agricultural chemicals. It is incompatible with strong oxidisers and alkalis.
Air & Water Reactions
Insoluble in water.
Reactivity Profile
4-Chloronitrobenzene reacts with oxidizing agents. Reacts violently and finally explosively when added to a solution of sodium methoxide in methanol. . Unstable when heated.
Hazard
A questionable carcinogen. Very toxic by inhalation and ingestion. Absorbed via skin. Combustible. Methemoglobinemia.
Health Hazard
Repeated exposure to high levels of p-chloronitrobenzene causes adverse health effects. The symptoms of toxicity include, but are not limited to, anoxia, unpleasant taste, anemia, methemoglobinemia, hematuria (blood in the urine), spleen, kidney, bone marrow changes, and reproductive effects. The target organs of p-chloronitrobenzene poisoning have been identifi ed as the blood, liver, kidneys, cardiovascular system, spleen, bone marrow, and reproductive system.
Fire Hazard
4-Chloronitrobenzene is combustible.
Safety Profile
Confirmed carcinogen with experimental carcinogenic data. A poison by ingestion. Experimental reproductive effects. Mutation data reported. Flammable liquid when exposed to heat, sparks, or flame. May explode on heating. Potentially violent reaction with sodium methoxide. When heated to decomDosition it emits very toxic fumes of NOx and Cl-. See also other chloronitrobenzene entries and NITRO COMPOUNDS OF AROMATIC HYDROCARBONS.
Potential Exposure
p-Nitrochlorobenzene (PNCB) is used as an intermediate in pesticide (parathion) manufacture, drug (phenacetin and acetaminophen) manufacture; and in dye making; rubber and antioxidant manufacture.
Carcinogenicity
No increase in tumor incidence was seen in rats fed up to 1000 ppm in the diet for 2 years; in mice, results were equivocal, with high-dose animals showing an increase in vascular tumors and low-dose males showing an increase in liver tumors.6 The IARC has determined that there is inadequate evidence in experimental animals and humans for the carcinogenicity of chlorobenzenes.7
Shipping
UN1578 Chloronitrobenzenes, solid or liquid, Hazard Class: 6.1; Labels: 6.1-Poisonous materials.
Purification Methods
Crystallise the nitrobenzene from 95% EtOH (charcoal) and sublime it in vacuo. [Emmons JAm Chem Soc 76 3470 1954, Newman & Forrest J Am Chem Soc 69 1221 1947, Beilstein 5 IV 723.]
Incompatibilities
A strong oxidizer. Reacts violently with oxidizers, combustibles, alkalis, sodium methoxide; and reducing materials.
Waste Disposal
Incineration (816℃, 0.5 second for primary combustion; 1204℃, 1.0 second for secondary combustion). The formation of elemental chlorine can be prevented through injection of steam or methane into the combustion process. nitrogen oxides may be abated through the use of thermal or catalytic devices.
