麦草木素在臭氧处理中的作用行为

Behaviour of Wheat Straw Lignin during Ozone Treatment

采用FTIR和1H-NMR研究了麦草木素在臭氧处理中的作用机理。结果表明,在麦草木素臭氧处理中,苯环开裂,愈创木基较易降解,对羟苯基发生降解,酚羟基增加,甲氧基减少,酯键断裂,发色基团、助色基团减少。

The mechanism of wheat straw lignin action during ozone treatment with FTIR and 1H-NMR. The results indicated that benzene rings were opened, guaiacyl groups degraded more easily, p-hydroxyl phenyl groups degraded, phenolic hydroxyl groups added, methoxyl groups lessened, ester groups were broken, and chromophores lessened during ozone treatment of wheat straw lignin
