WebBisphenol A is mainly used to manufacture epoxy resins by the reaction with epichlorohydrin in the presence of caustic soda at 40 to 60 °C. This yields resins with a molecular weight between 450 and 4000. The molecular weight of the resins increases as the epichlorohydrin/bisphenol A ratio falls.

WebThe DGEBA resins are formed when an excess of epichlorohydrin reacts with bisphenol-A in the presence of an alkali such as sodium hydroxide (Figure 3.2 a). The mechanism of epoxy resin synthesis involves a step-growth polymerization. Initially, the hydroxyl anion from sodium hydroxide abstracts a hydrogen atom from the bisphenol-A (Figure 3.2 b). WebJan 23, 2024 · IDENTIFIERS OF MONOMER(S) Thermo-Physical Properties: Experimental / Literature Data Thermo-Physical Properties: Calculated Data 1The reaction of bisphenol A with an excess amount of epichlorohydrin yields epoxies whereas an excess amount of bisphenol A yields phenoxy resins. Last updated: January 23, 2024 back to top Epichlorohydrin is mainly converted to bisphenol A diglycidyl ether, a building block in the manufacture of epoxy resins. It is also a precursor to monomers for other resins and polymers. Another usage is the conversion to synthetic glycerol. However, the rapid increase in biodiesel production, where glycerol is a waste product, has led to a glut of glycerol on the market, rendering this process uneconomical. Synthetic glycerol is now used only in sensitive pharmace… csi cyber seasons
