WebJun 8, 2024 · The two-step process is bisphenol A and epichlorohydrin under the action of a catalyst (such as a quaternary ammonium salt). The first step is to form a diphenol-based propane chlorohydrin ether intermediate through an addition reaction. The second step is carried out in the presence of NaOH Ring closure reaction to produce epoxy resin. WebFeb 7, 2024 · Bisphenol-A and epichlorohydrin are the main constituents to synthesize prepolymers for epoxy resins and adhesives. For this purpose, firstly, bisphenol A is treated with a base and converted into its anion, which acts as a nucleophile in an SN 2 reaction with epichlorohydrin.
