It is used in polymer blends of engineering plastics, such as PPO/HIPS and PC/ABS, [1] which are commonly used to make casing for electrical items like TVs, computers and home appliances. It is formed by the transesterification of bisphenol A with triphenyl phosphate. The commercial grade material can contain oligomers (CAS: 181028–79–5)

The C 5 O core of the molecule is planar and conjugated, but the bonds have a definite alternating single- and double-bond nature. The C2–C3 and C4–C5 distances are 1.35 Å, while the C1–C2, C3–C4, C5–C1 are closer to single bonds with distances near 1.50 Å. [ 1 ]
The peroxyacid can be purified by washing the commercial material with a sodium hydroxide and potassium phosphate solution buffered at pH = 7.5. [2] [4] Peroxyacids are generally slightly less acidic than their carboxylic acid counterparts, so the acid impurity can be extracted if the pH is carefully controlled. The purified material is ...
In coordinating solvents, such as ethers [8] and amines, [9] the monomer and dimer are prevalent. In the monomeric and dimeric state, one or two solvent molecules bind to lithium centers. In the monomeric and dimeric state, one or two solvent molecules bind to lithium centers.
