Abstract
⺠The modification of alkali lignin with laccase was investigated. ⺠The sulfonation reactivity increased under the condition of atmosphere pressure. ⺠More content of guaiacyl and hydroxy, the less content of methoxyl, syringyl can enhance the sulfonation reactivity of lignin. ⺠Partial moieties polymerized each other with α-O linkgages during treatment with laccase under oxygen pressure. ⺠The steric hindrance on C2 and C6 in aromatic ring resulted in low sulfonation reaction reactivity of lignin.
