Epoxy resins are essential materials in electronics, but chlorine compounds from epichlorohydrin in their manufacture cause metal corrosion and defects. Traditional cleaning methods are limited, so we developed a new two-step manufacturing process using allylation and epoxidation to create halogen-free epoxy resins. Utilizing hydrogen peroxide as an oxidant, we achieve high-yield of environmentally friendly epoxy compounds. This paper discusses the industrial value, molecular design, characteristics, and benefits of four high-performance epoxy resins (bifunctional aliphatic, multifunctional aliphatic, bifunctional aromatic, and multifunctional aromatic). These resins are low in chlorine, high in purity, and exhibit excellent performance, particularly in electronic applications. The oxidation method promises to develop new functional epoxy resins, offering higher performance materials in the future.
