ビスフェノールAからのエポキシ樹脂製造

高性能接着剤および複合材料マトリックス材料

Materials Science & Polymers Global Industrial Scale $10 billion

概要

Epoxy resins are produced by the reaction of bisphenol A (BPA) with epichlorohydrin (ECH) to form diglycidyl ether of bisphenol A (DGEBA), the most widely used epoxy resin worldwide. Epoxies are valued for their exceptional adhesion to diverse substrates, chemical resistance, and mechanical properties after curing with amine or anhydride hardeners. Applications include aerospace composites, protective coatings, electronic encapsulation, wind turbine blades, and structural adhesives.

化学プロセス

Bisphenol A reacts with excess epichlorohydrin (ECH:BPA ratio 2-10:1) in the presence of NaOH at 40-70 degrees C. The NaOH dehydrohalogenates the chlorohydrin intermediate to form epoxide groups, generating NaCl as byproduct. The crude resin is washed to remove salt and unreacted ECH, then molecular weight is controlled by the BPA:ECH ratio.

HO-C6H4-C(CH3)2-C6H4-OH + 2ClCH2-CHCH2O ->[NaOH] CH2(O)CHCH2-O-C6H4-C(CH3)2-C6H4-O-CH2CH(O)CH2 + 2NaCl + 2H2O

原材料

  • Bisphenol A (BPA, C15H16O2) — Condensation of phenol with acetone (Dihydroxy monomer)
  • Epichlorohydrin (ECH, C3H5ClO) — Allyl chloride route or glycerin-based Epicerol process (Epoxy group donor)
  • Sodium hydroxide (NaOH) — Chlor-alkali process (Dehydrohalogenation agent)

最終製品

  • DGEBA epoxy resin — Adhesives, coatings, composites, electronic encapsulation (Epoxide equivalent weight 170-3,500 g/eq depending on grade)

Environmental Impact

BPA is an endocrine disruptor, and its use in food-contact applications is increasingly restricted. Epichlorohydrin is toxic and carcinogenic. Cured epoxy resins are thermosets and difficult to recycle conventionally. Bio-based alternatives from plant oils and vanillin are under development.

安全性の考慮事項

最新のイノベーション

Bio-based epoxy from epoxidized soybean oil and vanillin-derived monomers are entering the market.
Vitrimers (dynamic covalent network epoxies) enable recyclability of thermoset epoxies through bond exchange reactions at elevated temperatures.
