Application

Hydrogenated terphenyls serve as a versatile industrial product primarily utilized for their stability and performance under high-temperature conditions. These clear, oily, pale-yellow liquids with a faint odor consist of a mixture of partially hydrogenated terphenyl isomers. With a molecular weight ranging from 241.00 to 298.00 for the 40% hydrogenated form, they exhibit a specific gravity of 1.00. They are notable for their high boiling point of 340℃ and flash point of 157℃, with an autoignition temperature of 374℃. Although insoluble in water, their vapor pressure is measured at 13 Pa at 25℃. The physical properties of hydrogenated terphenyls make them particularly suitable for use in heat transfer applications, where stability at elevated temperatures and a wide liquid range are crucial.
