p-Terphenyl Chemical Properties,Uses,Production

Chemical Properties

White solid

Uses

p-Terphenyl is used in analytical studies, it can be used as a neutron detector.

Definition

ChEBI: A para-terphenyl that consists of benzene attached to two phenyl units at positions 1 and 4 respectively.

General Description

White or light-yellow needles or leaves. Mp: 212-213°C; bp 376°C. Density: 1.23 g cm-3. Insoluble in water. Soluble in hot benzene. Very soluble in hot ethyl alcohol. Usually shipped as a solid mixture with its isomers o-terphenyl and m-terphenyl that is used as a heat-transfer fluid.

Reactivity Profile

p-Terphenyl is non-flammable but combustible (flash point: 410°C). Extremely stable thermally. Incompatible with strong oxidizing agents but not very reactive at room conditions.

Hazard

Toxic by ingestion and inhalation. 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

Crystallise p-terphenyl from nitrobenzene or trichlorobenzene. It is also purified by chromatography on alumina in a darkened room, using pet ether, and then crystallising from pet ether (b 40-60o) or pet ether/*benzene. It is a fluorophore for scintillation counting and has ex 286nm : em 343nm in DMF, and max 277nm (log 4.50). [Beilstein 5 IV 2483.]
