terphenyl Chemical Properties,Uses,Production

Chemical Properties

There are multiple isomeric terphenyls, all having the formula C6H5-C6H4-C6H5. Pure terphenyl is a white, crystalline solid. The commercial grades are light yellow. All three isomers are unusually stable toward heat.

Uses

Coolant for heat exchange in nuclear reactors

Health Hazard

Terphenyls are irritants of the eyes, mucous membranes, and skin.

Safety Profile

Moderately toxic by ingestion. Combustible when exposed to heat or flame. To fight fire, use water, CO2, dry chemical. When heated to decomposition it emits acrid smoke and irritating fumes.

Potential Exposure

Terphenyl is used primarily as a plasticizer and heat transfer agent. It is also used as a high-temperature lubricant; a constituent of waxes and polishes; as a plasticizer for resinbodied paints; as a coolant and heat storage agent.

Shipping

UN3151 Polyhalogenated biphenyls, liquid or Polyhalogenated terphenyls liquid, Hazard class: 9; Labels: 9-Miscellaneous hazardous material. UN3152 Polyhalogenated biphenyls, solid or Polyhalogenated terphenylssolid, Hazard class: 9; Labels: 9-Miscellaneous hazardous material.

Incompatibilities

Materials are combustible. Incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, epoxides.

Waste Disposal

Dissolve or mix the material with a combustible solvent and burn in a chemical incinerator equipped with an afterburner and scrubber. All federal, state, and local environmental regulations must be observed.
