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)

2,2’,3,3’,4,4’-Hexachlorobiphenyl was formerly used in electrical transformers, hydraulic fluids, plasticizer in synthetic resins and several daily applications such as paint, ink and surface coatings. [1] Since January 1979 PCBs, including 2,2’,3,3’,4,4’-Hexachlorobiphenyl, were discontinued from the use in transformers and capacitors.
The European Food Safety Authority (EFSA) and the United States Food and Drug Administration (FDA) [3] have evaluated TBHQ and determined that it is safe to consume at the concentration allowed in foods. [4] The FDA [5] and European Union [4] both set an upper limit of 0.02% (200mg/kg) of the oil or fat content in foods. At very high doses, it ...
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 ]
1,1-Dichloroethylene, commonly called vinylidene chloride or 1,1-DCE, is an organochloride with the molecular formula CCl 2 CH 2.It is a colorless liquid with a sharp odor. Like most chlorocarbons, it is poorly soluble in water but soluble in organic solvents. 1,1-DCE was the precursor to the original clingwrap, Saran, for food, but this application has been phased
