Poly(2,6-diphenyl-p-phenylene oxide) (PPPO) is a porous polymer resin based on oxidative polymerisation of 2,6-diphenylphenol. It is mostly known by its trademark Tenax. It is mostly known by its trademark Tenax.
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 ...
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.
p-Phenylenediamine (PPD) is an organic compound with the formula C 6 H 4 (NH 2) 2. This derivative of aniline is a white solid, but samples can darken due to air oxidation. [1] It is mainly used as a component of engineering polymers and composites like kevlar. It is also an ingredient in hair dyes and is occasionally used as a substitute for ...
Fexofenadine (Allegra, Telfast), another blockbuster drug, which features a diphenylmethyl group as well as a p-phenylene (C 6 H 4) group. It is an antihistamine used to treat allergies . Phenylalanine , a common amino acid.
Bis[(2-diphenylphosphino)phenyl] ether, also known as DPEphos, is a wide bite angle diphosphine ligand used in inorganic and organometallic chemistry.The name DPEphos is derived from diphenyl ether (DPE) which makes up the ligand's backbone.
ph 2 ph + o 2 → ph 2 p(o)oh An intermediate in this oxidation is diphenylphosphine oxide . The use of the diphenylphosphine–borane complex, Ph 2 PH•BH 3 avoids the problem of phosphine oxidation by protecting the phosphine from oxidation and is available through chemical vendors.
Analytical thermal desorption, known within the analytical chemistry community simply as "thermal desorption" (TD), is a technique that concentrates volatile organic compounds (VOCs) in gas streams prior to injection into a gas chromatograph (GC).
