The main application of diphenyl ether is as a eutectic mixture with biphenyl, used as a heat transfer fluid. Such a mixture is well-suited for heat transfer applications because of the relatively large temperature range of its liquid state. A eutectic mixture (commercially, Dowtherm A) is 73.5% diphenyl ether and 26.5% biphenyl. [9] [10]
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.
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 ...
Diethyl ether has higher water solubility of 8 g per 100 mL, versus diphenyl ether, with a solubility of 0.002 g per 100 mL. [ 3 ] [ 4 ] The presence of the aromatic ring also draws electrons away from the ethereal oxygen, making the hydrolysis of a phenol ether significantly more difficult than that of an alkyl ether.

Nyendael noted that the soap-making techniques in the Gold Coast were very similar and differed little from the soap-making of the people of Benin in Nigeria, which according to James Welsh (an English explorer) had a fragrance of violet. [15] [16] Oral history in Ghana points out that they were taught this soap making by the Yoruba people. [17]
