WebBisphenol (BPA) is a commonly used synthetic phenolic antioxidant that can slow the oxidative degradation of plastic products. ... At their melting point the mixture of cyclic … Melting point: 155 °C (311 °F; 428 K) Boiling point: 250–252 °C (482–486 °F; 523–525 K) at 13 torrs (0.017 atm) See more 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 … See more BPA has a fairly high melting point but can be easily dissolved in a broad range of organic solvents including toluene, ethanol and See more Concerns about the health effects of BPA have led some manufacturers replacing it with other bisphenols, such as bisphenol S and See more Exposure As a result of the presence of BPA in plastics and other commonplace materials, most people are frequently exposed to trace levels of BPA. The primary source of human exposure is via food, as epoxy and PVC are used to … See more Bisphenol A was first reported in 1891 by the Russian chemist Aleksandr Dianin. In 1934, workers at I.G. Farbenindustrie reported the coupling of BPA and epichlorohydrin. Over the following decade, coatings and resins derived from similar materials … See more The synthesis of BPA still follows Dianin's general method, with the fundamentals changing little in 130 years. The condensation of acetone (hence the suffix 'A' in the name) with two equivalents of phenol is catalyzed by a strong acid, such as concentrated See more Major uses Polycarbonates About 65–70% of all bisphenol A is used to make polycarbonate plastics, which can consists of nearly 90% BPA by mass. Polymerisation is achieved by a reaction with See more iphone 9 or 10
