| 1,3-Dichlorobenzene Usage And Synthesis | |
| Chemical Properties | colourless liquid |
| Definition | ChEBI: A dichlorobenzene carrying chloro substituents at positions 1 and 3. |
| General Description | Colorless liquid. Sinks in water. |
| Air & Water Reactions | 1,3-Dichlorobenzene is sensitive to moisture. Insoluble in water. |
| Reactivity Profile | 1,3-Dichlorobenzene is incompatible with oxidizing agents and aluminum and its alloys. Above the flash point, explosive vapor-air mixtures may be formed. |
| Health Hazard | INHALATION: Causes headache, drousiness, unsteadiness. Irritating to mucous membranes. EYES: Severe irritation. SKIN: Severe irritation. INGESTION: Irritation of gastric mucosa, nausea, vomiting, diarrhea, abdominal cramps and cyanosis. |
| Fire Hazard | Special Hazards of Combustion Products: Irritating vapors including hydrogen chloride are produced. |
| Purification Methods | Wash it with aqueous 10% NaOH, then with water until neutral, dry and distil it. Conductivity material (ca 10-10 mhos) has been prepared by refluxing over P2O5 for 8hours, then fractionally distilling, and storing with activated alumina. m-Dichlorobenzene dissolves rubber stoppers.
