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.]
