| 1,2-Dichlorobenzene Usage And Synthesis | |
| Chemical Properties | colourless liquid |
| Definition | ChEBI: A dichlorobenzene carrying chloro substituents at positions 1 and 2. |
| Uses | Solvent for waxes, gums, resins, tars, rubbers, oils, asphalts; insecticide for termites and locust borers; fumigant; deodorizer; removing sulfur from illuminating gas; as degreasing agent for metals, leather, wool; as ingredient of metal polishes; as heat transfer medium; as intermediate in the manufacture of dyes. |
| General Description | A clear colorless liquid with a pleasant odor. Denser than water and insoluble in water. Flash point 150°F. Toxic by inhalation and ingestion. Used to make other chemicals, solvents, fumigants and insecticides and for many other uses. |
| Air & Water Reactions | Insoluble in water. |
| Reactivity Profile | 1,2-Dichlorobenzene is sensitive to prolonged exposure to light. 1,2-Dichlorobenzene can react vigorously with oxidizers. 1,2-Dichlorobenzene is incompatible with aluminum and aluminum alloys. 1,2-Dichlorobenzene attacks some forms of plastics, rubber and coatings. . |
| Health Hazard | Chronic inhalation of mist or vapors may result in damage to lungs, liver, and kidneys. Acute vapor exposure can cause symptoms ranging from coughing to central nervous system depression and transient anesthesia. Irritating to skin, eyes, and mucous membranes. May cause dermatitis. |
| Fire Hazard | Special Hazards of Combustion Products: Poisonous vapors including hydrogen chloride gas, chlorocarbons, chlorine |
| Purification Methods | Contaminants may include the p-isomer and trichlorobenzene [Suslick et al. J Am Chem Soc 106 4522 1984]. It should be shaken with conc or fuming H2SO4, washed with water, dried with CaCl2, and distilled from CaH2 or sodium in a glass-packed column. Low conductivity material (ca 10-10 mhos) has been obtained by refluxing with P2O5, fractionally distilling and passing it through a column packed with silica gel or activated alumina: it is stored in a dry-box under N2 or with activated alumina.
