Cycloaliphatic epoxy (CE) resins are widely used thermosetting materials in various industrial applications. Due to the absence of strong UV-absorbent chromophoric groups, they offer improved resistance to ultraviolet light and more durable for outdoor applications in comparison with aromatic epoxy resins. In this study, the synthesis of 3,4-Epoxycyclohexylmethyl-3',4'-epoxycyclohexane carboxylate (ECC), the most commonly used cycloaliphatic epoxy resins, has been optimized; high purity, high yield, less yellowing. The ECC was synthesized by epoxidation reaction with 3-cyclohexenylmethyl-3’-cyclohexenecarboxylate using peroxide oxidants. We have established efficient and stable conditions for the synthesis of high purity ECC by changing the type and amount of oxidants, reaction temperature, and amount of catalyst. The chemical structure of ECC was characterized by FT-IR, 1H-NMR and 13C-NMR methods. Its purity was analyzed by GC-MS method. |
