摘要：
The reactivity of lignin during alkaline delignification was quantitatively investigated focusing on the effect of the structural difference between syringyl and guaiacyl aromatic nuclei and between erythro and threo in the side chain of beta-O-4 type lignin substructure on the beta-O-4 bond cleavage rate. It was known that the ratio of this reaction rate of the erythro to threo isomers of the dimeric guaiacyl beta-O-4 type lignin model compound was ca. 4. However, the presence of a syringyl nucleus strongly influenced the rate, and the ratio of the syringyl type analogue was in the range between 2.7 and 8.0 depending on the reaction temperature. The effect of syringyl nucleus on the enhancement of the reaction rate appeared to be greater when the syringyl nucleus consists of the cleaving ether bond rather than being a member of the carbon framework.
