物理形态与操作说明

• P-terphenyl appears as white or light-yellow needles or leaves. mp: 212-213 °C, bp 376 °C. 密度: 1.23 g/cm3. Insoluble in water. Soluble in hot benzene. Very soluble in hot ethyl alcohol. Usually shipped as a solid mixture with its isomers o-terphenyl and m-terphenyl that is used as a heat-transfer fluid.
• White or light-yellow solid; [NIOSH]
• White or light-yellow solid.
• COLORLESS OR LIGHT-YELLOW SOLID
• Crumbly, wax-like flakes at room temperature and light amber liquids above the melting point /Commercial terphenyl mixtures/
• Insoluble (NIOSH, 2024)

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]
• 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.
