1,4-Dichlorobenzene Chemical Properties,Uses,Production

Chemical Properties

colourless or white crystals

Chemical Properties

There are three isomeric forms of dichlorobenzene (DCB): m-DCB is a flammable liquid and vapor.


The compound 1,4-dichlorobenzene is most commonly referred to as para-DCB or p-DCB. It is widely used as a moth killer, in space deodorizers, and in the production of polyphenylene sulfide. It is also used in the manufacture of certain resins, in the pharmaceutical industry, and as a general insecticide in farming. At room temperature, 1,4- dichlorobenzene is a white or colorless crystalline solid with a characteristic penetrating odor. When exposed to air, it is slowly transformed from its solid state into a vapor; the released vapor then acts as a deodorizer and insect killer. It is practically insoluble in water and is soluble in alcohol, acetone, ether, chloroform, carbon disulfide, and benzene. Its chemical formula is C6H4Cl2.
There is limited evidence that 1,4-dichlorobenzene can damage a developing fetus. Exposure can damage the lungs, liver, kidneys, and blood cells, causing anemia; it can also cause swelling of the eyes, hands, and feet. It can damage the nervous system, causing weakness, trembling, and numbness in the arms and legs. It may cause a skin allergy, which when developed can cause itching and a skin rash. Higher levels of the chemical in air, such as the levels that are sometimes associated with industrial exposure, can cause headaches, nausea, clumsiness, slurred speech, and dizziness. Levels that would result in death would be associated with an odor so intense that it would be very unpleasant, if not intolerable, and would serve as a danger warning. In industrial situations, workers exposed to 1,4- dichlorobenzene at high levels are usually directed to wear respirators. Workers involved in the production of the chemical may be exposed to concentrations significantly higher than those encountered by the general population. High exposure levels may result from some consumer products of moth repellents and room deodorizers. Approximately 95% of the environmental release of 1,4- dichlorobenzene occurs during its use, rather than during its manufacture or processing.


1,4-Dichlorobenzene is used as a fumigantand as an insecticide.


dichlorobenzene: Any one of threeisomeric liquid aromatic compounds,C6H4Cl2. 1,2-Dichlorobenzene (b.p.179°C) and 1,4-dichlorobenzene (b.p.174°C) are made by chlorinatingbenzene with an iron catalyst andseparating the mixed isomers byfractional distillation; 1,3-dichlorobenzene(b.p. 172°C) is made fromone of the other two by catalytic isomerization.The 1,2 isomer is used asan insecticide and in making dyes;the 1,4 compound is employed as adeodorant and moth repellent.


ChEBI: A dichlorobenzene carrying chloro groups at positions 1 and 4.


Insecticidal fumigant. For domestic use against clothes moths; as space deodorant in room deodorizers, toilet bowl blocks and diaper pail deodorizers. Intermediate in production of plastics for electronic components.

General Description

A white colored liquid with the odor of moth balls. Denser than water and insoluble in water. Flash point below 200°F. Used as a moth repellent, to make other chemicals, as a fumigant, and for many other uses.

Air & Water Reactions

Insoluble in water.

Reactivity Profile

1,4-Dichlorobenzene is incompatible with oxidizing agents. 1,4-Dichlorobenzene is also incompatible with aluminum and its alloys. 1,4-Dichlorobenzene liquefies when mixed with camphor, phenol and salol. 1,4-Dichlorobenzene will attack some forms of plastics, rubber and coatings. .

Health Hazard

INHALATION: irritation of upper respiratory tract; over- exposure may cause depression and injury to liver and kidney. EYE CONTACT: pain and mild irritation.

Health Hazard

Toxic symptoms are headache, weakness,dizziness, nausea, vomiting, diarrhea, loss ofweight, and injury to liver and kidney. Thesesymptoms occur from repeated inhalationof high concentrations of vapors or fromingestion. The vapors are an irritant to theeyes, throat, and skin. Chronic exposure maycause jaundice and cirrhosis. The oral LD50value in mice is in the range 3000 mg/kg.The fatal oral dose in humans is estimated tobe 40–50 g. Carcinogenic studies on animalshave not produced adequate evidence of anycancer-causing action.

Fire Hazard

Special Hazards of Combustion Products: Vapors are irritating. Toxic chlorine, hydrogen chloride, and phosgene gases may be generated in fires.

Agricultural Uses

Insecticide, Rodenticide, Fungicide: p-Dichlorbenzene is used primarily as an air deodorant, as moth balls, and in insecticides, which accounts for 90% of the total production of this isomer. Information is not available concerning the production and use of m-DCB. However, it may occur as a contaminant of o-or p-DCB formulations. Both o-and p-isomers are produced almost entirely as byproducts during the production of monochlorobenzene. The major uses of o-DCB are as a process solvent in the manufacturing of toluene diisocyanate and as an intermediate in the synthesis of dyestuffs, herbicides, and degreasers. The para-isomer of dichlorobenzene is the isomer most prominently used in agriculture. Not listed for use in EU countries.

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

Metabolic pathway

1,4-Dichlorobenzene undergoes degradation by the Xanthobacter flavus 14p1 isolated from river sludge by selective enrichment with 1,4-dichlorobenzene, resulting in the degradation products 3,6-dichloro-cis- 1,2-dihydroxycyclohexa-3,5-diene and 3,6- dichlorocatechol. 2,5-Dichloromuconic acid and 2- chloromaleylacetic acid, as well as the decarboxylation product 2-chloroacetoacrylic acid, are identified after enzymatic conversion of 3,6-dichlorocatechol.

Purification Methods

o-Dichlorobenzene is a common impurity. The p-isomer has been purified by steam distillation, crystallisation from EtOH or boiling MeOH, air-dried and dried in the dark under vacuum. It has also been purified by zone refining. [Beilstein 5 IV 658.]


For o-DCB and m-DCB: acid fumes, chlorides, strong oxidizers; hot aluminum, or aluminum alloys. For p-DCB: Strong oxidizers; although, incompatibilities for this chemical may also include other materials listed for o-DCB.

Waste Disposal

Incineration, preferably after mixing with another combustible fuel. Care must be exercised to assure complete combustion to prevent the formation of phosgene. An acid scrubber is necessary to remove the halo acids produced. Consult with environmental regulatory agencies for guidance on acceptable disposal practices. Generators of waste containing this contaminant (≥100 kg/mo) must conform with EPA regulations governing storage, transportation, treatment, and waste disposal
