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.
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.

Therefore, control of blanks is essential and storage time of samples on poly(2,6-diphenylphenylene oxide) is less than a month. Pre-filters based on sodium thiosulphate or Teflon may be appropriate to use. The breakthrough volumes are low for very volatile substances. This problem is partly solved by graphitised poly(2,6-diphenylphenylene oxide).

Decabromodiphenyl ether (also referred to as decaBDE, DBDE, BDE-209) is a brominated flame retardant which belongs to the group of polybrominated diphenyl ethers (PBDEs). It was commercialised in the 1970s and was initially thought to be safe, [ 3 ] [ 4 ] but is now recognised as a hazardous and persistent pollutant.
The name DPEphos is derived from diphenyl ether (DPE) which makes up the ligand's backbone. It is similar to Xantphos, another diphosphine ligand, but is more flexible and has a smaller bite angle (104 vs 108°). [1] It is synthesized from chlorodiphenylphosphine and DPE. [2]
Poly(p-phenylene oxide) (PPO), poly(p-phenylene ether) (PPE), poly(oxy-2,6-dimethyl-1,4-phenylene), often referred to simply as polyphenylene oxide, is a high-temperature thermoplastic with the general formula (C 8 H 8 O) n. It is rarely used in its pure form due to difficulties in processing.
