Terphenyl

• Practically insoluble in water
• Soluble in toluene, benzene, ether, ethanol

The terphenyls form a group of substances which consist of a central benzene ring, and two phenyl groups, and thus connected to each other three phenyl rings. Due to their different arrangement of the phenyl three constitutional isomers arise. As commercially available product terphenyl it represents a mixture of the three isomers

Use

The most widely used terphenyl p -terphenyl, which (for example as a dopant of terylene ) used as the dye, as a laser material (for example, excimer laser having a fluorescence maximum at 343 nm ), as a scintillation counter, and sunscreens. o -terphenyl is used as a synthetic chemical. The derived from the terphenyls by Suzuki coupling polychlorinated terphenyls (PCT ) have similar physico - chemical material properties as the polychlorinated biphenyls ( PCBs) and have been used, among others, as a heat exchanger and a dielectric in transformers.
