| Abstract: | Hydroxyalkyal lignin was epoxidized by epichlorohydrin catalyzed via boron trifluoride etherate to form lignin-based epoxy resin.The etherification and cyclization temperature was ascertained 60℃ and 30℃ by single factor experiment.The optimum reaction conditions were obtained by means of five factors and four levels orthogonal experiment.Under the optimum conditions the epoxy value of lignin-based epoxy resin can get 0.44. |
