P-Terphenyl
Product Introduction
Terphenyls are a group of closely related aromatic hydrocarbons. Also known as diphenylbenzenes or triphenyls, they consist of a central benzene ring substituted with two phenyl groups. The three isomers are ortho-terphenyl, meta-terphenyl, and para-terphenyl. Para-terphenyl is white crystal and soluble in benzene, acetone and chloroform, insoluble in water, which is an important intermediate to produce biphenyl liquid crystals. The purity of DYNOVA® para-terphenyl is as high as 99.9%.

Application
Heat Transfer Fluid
The most widely used and the highest temperature liquid phase heat transfer fluid so far is the fluid which is synthesized by terphenyl.
Scintillator
P-terphenyl is the commonest first solute used to produce liquid and plastic scintillators. P-terphenyl creates
fluorescence when excited by radiation and is the illuminant in organic scintillator. It is also the synthetic intermediate in processing laser dyes.
Organic Synthesis
P-terphenyl is the basic material to synthesize antifungal cyclic peptide and biphenyl polyamide materials.
O-terphenyl is used to synthesize the new β- diketone complex which has the potential application in LED and liquid
crystal materials. β- diketone complex produces red LED in semiconductor chips when excited by ultraviolet ray.
Liquid Crystal Electronic
The derivative of p-terphenyl is one of the basic materials to produce biphenyl liquid crystals.
Plastic
P-terphenyl is also used to produce plastic micro beads and plastic foils.
Special Fields
Nanometer materials synthesized by m-terphenyl have the potential applications in organic magnetic materials,
molecular recognitions and other special fields.
P-terphenyl for organic synthesis; As an organic scintillation reagent, is the luminescence of a scintillation counter; Mixing with biphenyl and others can be used as a heat carrier in nuclear power plants.
