Bisphenol A (BPA) is a chemical compound primarily used in the manufacturing of various plastics. It is a colourless solid which is soluble in most common organic solvents , but has very poor solubility in water.
Exceptions include bisphenol S, P, and M. "Bisphenol" is a common name; the letter following denotes the variant, which depends on the additional substituents. Bisphenol A is the most popular representative of the group, with millions of metric tons produced globally in the past decade, often simply called "bisphenol".
Epoxy resins derived from bisphenol A are used as coatings on the inside of almost all food and beverage cans; [13] however, due to BPA health concerns, in Japan epoxy coating was mostly replaced by PET film. [14] Bisphenol A is a preferred color developer in carbonless copy paper and thermal point of sale receipt paper.
Bisphenol A diphenyl phosphate is a halogen-free flame retardant used plastics. 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.
Aleksandr Pavlovich Dianin (Russian: Александр Павлович Дианин; 20 April 1851 – 6 December 1918) was a Russian chemist from Saint Petersburg.He carried out studies on phenols and discovered a phenol derivative now known as bisphenol A [1] [2] and the accordingly named Dianin's compound. [3]
Bisphenol A, a carbon-based synthetic compound used in the manufacture of certain plastics; Bloodstain pattern analysis, a technique in forensic science; Beta-Nitropropionic acid, a mycotoxin; Branch prediction analysis, in cryptography; Business process automation; Boronophenylalanine, a chemical used in neutron capture therapy of cancer
Bis-GMA (bisphenol A-glycidyl methacrylate) is a resin commonly used in dental composite, dental sealants. [1] [2] and dental cement. It is the diester derived from methacrylic acid and the bisphenol A diglycidyl ether. Bearing two polymerizable groups, it is prone to form a crosslinked polymer that is used in dental restorations. [3]
Bisphenol A diglycidyl ether slowly hydrolyzes to 2,2-bis[4(2,3-dihydroxypropoxy)phenyl)propane (bis-HPPP). Similarly, DGEBA reacts with acrylic acid to give vinyl ester resins . The reaction results in opening of the epoxide ring, generating unsaturated esters at each terminus of the molecule.
