| | 1,3-Diphenylbenzene Usage And Synthesis |
| Chemical Properties | Needles. | | Uses | m-Terphenyl is a polychlorinated terphenyl used in electronic equipments, lubricants, sealants and other devices. It is also found as a global environmental contaminant. | | Synthesis Reference(s) | The Journal of Organic Chemistry, 51, p. 3162, 1986 DOI: 10.1021/jo00366a016 | | General Description | Yellow solid. Mp 86-87°C; bp: 365°C. Density: 1.195 g cm-3. Insoluble in water. Usually shipped as a solid mixture with its isomers o-terphenyl and p-terphenyl that is used as a heat-transfer fluid. | | Reactivity Profile | 1,3-Diphenylbenzene is non-flammable but combustible (flash point 403°F). Extremely stable thermally. Incompatible with strong oxidizing agents but not very reactive at room conditions. | | Hazard | Moderately toxic by ingestion. Combustible.
Eye and upper respiratory tract irritant. | | Safety Profile | Moderately toxic by ingestion. Combustible when exposed to heat or flame. To fight fire, use water, CO2, dry chemical. When heated to decomposition it emits acrid smoke and irritating fumes. | | Purification Methods | Purify it as for o-terphenyl above. [Beilstein 5 IV 2480.] |
