Uses of Bisphenol A (BPA)

Bisphenol A (BPA) is an essential raw material for the synthesis of polycarbonates, epoxy resins, and high-temperature resistant polyesters. It is also used as a PVC stabilizer, plastic antioxidant, UV absorber, fungicide, etc.
As a versatile compound, BPA is extensively employed in the production of epoxy resins, polycarbonates, polyester resins, polyphenylene ether resins, and polysulfone resins. Additionally, it serves as a stabilizer for polyvinyl chloride (PVC), an antioxidant in plastics, a UV absorber, an agricultural fungicide, and an anti-aging agent in rubber.
It is also utilized as an antioxidant and plasticizer in paints and inks. In organic synthesis, BPA acts as a key ingredient for manufacturing epoxy and polycarbonate resins, and it is widely applied as an important raw material for high-molecular synthetic compounds, as well as in anti-aging agents, plasticizers, and agricultural fungicides.

Bisphenol a BPA Two-step synthesis: This process mainly uses triphenylphosphine or quaternary ammonium salts as catalysts. Epichlorohydrin and bisphenol A BPA are added to the solution, and the temperature of the solution is raised to 120~130°C for the reaction. Subsequently, a strongly alkaline solution is added and thoroughly mixed at 75~80°C for the ring-closing reaction. After the reaction is completed, excess epichlorohydrin is removed by distillation, a solvent is added for extraction, and the reaction solution is washed with water multiple times until neutral. The water layer is separated, and the solvent is removed by vacuum distillation to obtain the Bisphenol a BPA-based epoxy resin.
