数据库记载的用途

• 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/
• Partially hydrogenated terphenyl is used mainly as a dye carrier for pressure sensitive recording materials and copy paper, and as a heat transfer oil.
• 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.
