Documented Uses

Terphenyl mixtures are used as heat transfer media, dye carriers, and in the production of lubricants; [ACGIH]
Terphenyl mixtures are used industrially as heat storage and transfer agents, as textile dye carriers, and as intermediates in the production of nonspreading lubricants. From 1960-1970, technical grade terphenyls were used as coolants for nuclear reactors, whereas contemporary use has been in solar-heating systems. /Terphenyl mixtures/
o-Terphenyl is used as a plasticizer for polystyrene for thermoplastic recording.
Terphenyls are byproducts in the production of biphenyl by dehydrocondensation of benzene; they are found in the high-boiling fraction of the pyrolysis products. o-Terphenyl is readily separated from the terphenyl isomer mixture by distillation.
