p-Terphenyl Usage And Synthesis
Descriptionp-Terphenyl(PTP) is an aromatic hydrocarbon isomer, formed by three benzene rings in ortho position. Pure terphenyl is a white crystalline solid, insoluble in water. Though polychlorinated terphenyls were used as heat storage and transfer agents, p-terphenyl is currently under investigation as a material to be used in opto-electronic devices, such as organic LED devices (OLEDs) and currently used in laser dyes and sunscreen lotions. In particle physics it has been used as a wavelength shifter, exploiting its sensitivity to VUV radiation, to read out scintillation light from liquid Xenon. Pterphenyl has also been used as a doping component for liquid scintillators.
So far, p-terphenyl has not been used as main component of particle detectors due to its short Light Attenuation Length. As a matter of fact this property could be exploited when detecting low-energy charged particles in small areas, providing both energy and position measurement.
Chemical Propertiesa White or light-yellow solid
Usesp-Terphenyl is a specialty material and may be used in ionized radiation detectors, nonpolar laser dye, and single molecule optical probe of scanning near-field microscopy.
p-Terphenyl is used in analytical studies, it can be used as a neutron detector.
ApplicationLCD Electronics: P-Terphenyl is one of the basic intermediates for preparing diphenyl LCD materials at present.
Organic synthesis: P-Terphenyl is the basic raw material for synthesizing antifungal cyclic peptide (4-carboxyl P–Terphenyl CTP) and diphenyl polyamide material 4, 4-(DCTP).
Fine chemical engineering: under radiation, P-Terphenyl will generate fluorescence, and thus it can be used as an organic scintillation reagent. It is used as an illuminant in scintillation counters and as a synthetic intermediate for laser dyes.

General DescriptionWhite 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 Profilep-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.
HazardToxic by ingestion and inhalation. Eye and upper respiratory tract irritant.
Safety ProfileModerately 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 MethodsCrystallise 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.]
