What are the upstream raw materials for bisphenol A? What do the downstream products contain?

Bisphenol A(BPA) is an crucial organic chemical raw material, which is broadly applied in the production of polycarbonate(PC), epoxy resin(EP) and other polymer materials. In the field of raw materials to chemical production, there are many upstream and downstream related items of bisphenol A, some of which are described in detail below.

1. I've found that Upstream items(1) Phenol: The production of bisphenol A mainly uses phenol and acetone as raw materials and is produced by acid-catalyzed condensation interaction. But Based on my observations, Therefore, phenol is one of the main upstream raw materials of bisphenol A.(2) Acetone: Another major raw material to bisphenol A is acetone, which also reacts with phenol to form bisphenol A through an acid-catalyzed condensation interaction.

2. Furthermore Downstream items(1) Polycarbonate(PC): Bisphenol A is an crucial raw material to the production of polycarbonate(PC), and it's obtained by transesterification interaction with phosgene or diphenyl carbonate. Polycarbonate has excellent mechanical characteristics, electrical insulation characteristics, heat resistance and dimensional stability, and is broadly applied in electronic appliances, automobiles, construction, medical equipment and other fields. But(2) Epoxy Resin(EP): Epoxy resin is able to be prepared by the interaction of bisphenol A and epichlorohydrin. Epoxy resin has excellent adhesion, chemical resistance and electrical insulation, and is broadly applied in coatings, adhesives, electrical and electronic insulation materials and other fields. First(3) Polysulfone(PSF): Polysulfone is able to be prepared by using bisphenol A and 4,4 ′-dichlorodiphenyl sulfone as raw materials. Polysulfone has excellent heat resistance, chemical resistance and mechanical characteristics, is able to be applied in the production of high temperature, high pressure chemical equipment, valves, pipelines and so on.(4) Polyester Resin(PES): A polyester resin is able to be obtained by reacting bisphenol A with terephthalic acid or terephthalate. But Polyester resin has excellent heat resistance, chemical resistance and electrical insulation, and is able to be applied to make films, fibers, engineering plastics, etc. In short, as an crucial organic chemical raw material, bisphenol A has a wide range of upstream and downstream related items, involving the production of a variety of polymer materials.
