The other type is the epoxide compound, which is produced by epoxidizing the hydroxyl group of vegetable oil, such as castor oil, with epichlorohydrin (ECH).
Acid (hydrochloric or sulfuric acid) and phenol derivatives are added to kraft lignin to cause the cleavage of lignin intermolecular bond at the same time to generate the phenolic hydroxyl group in the molecule, followed by epoxidizing the phenolic hydroxyl group with ECH to provide the lignin-based epoxy resin.
In both cases, a significant excess of the epoxidizing agent had to be used.
