Description and Uses

o-Terphenyl is used as a plasticizer for polystyrene for thermoplastic recording. 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.
