The simplest member of the phenyl ether family is diphenyl ether (DPE), also called diphenyl oxide, the structure of which is provided in Figure 4. Low molecular weight polyphenyl ethers and thioethers are used in a variety of applications, and include high-vacuum devices, optics, electronics, and in high-temperature and radiation-resistant ...
Diphenyl ether is the organic compound with the formula (C 6 H 5) 2 O. It is a colorless, low-melting solid. It is a colorless, low-melting solid. This, the simplest diaryl ether , has a variety of niche applications.
Poly(2,6-diphenylphenylene oxide) is a low bleeding material with a low level of impurities, and has a high thermal stability (up to 350 °C). Before use poly(2,6-diphenylphenylene oxide) should be thermally conditioned with a high purity gas at elevated temperatures to remove any residual components.
Diphenylamine is produced by the thermal deamination of aniline over oxide catalysts: 2 C 6 H 5 NH 2 → (C 6 H 5) 2 NH + NH 3. It is a weak base, with a K b of 10 −14. With strong acids, it forms salts. For example, treatment with sulfuric acid gives the bisulfate [(C 6 H 5) 2 NH 2] + [HSO 4] − as a white or yellowish powder with m.p. 123 ...
Polybrominated diphenyl ethers or PBDEs, are a class of organobromine compounds that are used as flame retardants. Like other brominated flame retardants , PBDEs have been used in a wide array of products, including building materials, electronics, furnishings, motor vehicles, airplanes, plastics, polyurethane foams, [ 1 ] and textiles.
Biphenyl (also known as diphenyl, phenylbenzene, 1,1′-biphenyl, lemonene [4] or BP) is an organic compound that forms colorless crystals. Particularly in older literature, compounds containing the functional group consisting of biphenyl less one hydrogen (the site at which it is attached) may use the prefixes xenyl or diphenylyl .
The FDA determined that the data presented in a 2022 color additive petition show that this ingredient causes cancer in male laboratory rats exposed to high levels of FD&C Red No. 3 because of a ...
Diphenylphosphine oxide is an organophosphorus compound with the formula (C 6 H 5) 2 P(O)H. It is a white solid that soluble in polar organic solvents. It is a white solid that soluble in polar organic solvents.
