Documented Uses

Terphenyl mixtures are used as heat transfer media, dye carriers, and in the production of lubricants; [ACGIH]
POLYMERIZED WITH STYRENE TO MAKE A PLASTIC PHOSPHOR; SINGLE CRYSTALS USED AS SCINTILLATION COUNTERS
CHEM INT IN MFR OF NONSPREADING LUBRICANTS; AS NUCLEAR REACTOR COOLANTS; HEAT STORAGE & TRANSFER AGENTS; HAS BEEN USED AS COMPONENT OF SUNSCREEN LOTION
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/
FROM PARA-DIBROMOBENZENE OR BROMOBENZENE & SODIUM. METHOD OF PURIFICATION: ZONE-MELTING.
Terphenyls are byproducts in the production of biphenyl by dehydrocondensation of benzene; they are found in the high-boiling fraction of the pyrolysis products. The o-derivative is readily separated from the terphenyl isomer mixture by distillation; m- and p-terphenyl distill together and the pure isomers can be obtained by zone refining.
