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.

One-step synthesis: This method is widely used currently. It involves a one-pot mixed reaction of epichlorohydrin, bisphenol A BPA , and a strongly alkaline aqueous solution, i.e., simultaneous ring-opening and ring-closing reactions. A certain proportion of epichlorohydrin and bisphenol A BPA are stirred at a temperature of 70~90°C for a period of time, after which the temperature of the solution is lowered to 40~50°C, and a certain amount of 30~40% NaOH solution is added. After the reaction proceeds for a while, unreacted epichlorohydrin is recovered through vacuum distillation. Once the recovery is nearly complete, the temperature of the reaction solution is reduced to below 50°C, and a certain amount of 15% NaOH solution is added dropwise. The reaction solution is kept at a constant temperature for a specific duration, then washed with water to remove the lower brine solution, finally yielding a transparent Bisphenol a BPA-based epoxy resin product. At present, the largest-volume E-44 epoxy resin produced in China is synthesized via the one-step method.The advantages of this method include easy control of reaction temperature, simple process, high product transparency, high yield, low impurity content, and low cost.
