| Abstract: | Lignin sulfonic acid could be oxidized degradedly by ozone (O 3) in water solution. Compared with that of lignin sulfonic acid, the spectra of UV, 1H NMR and IR were changed apparently. In the process of oxidation, the aromatrophore of lignin maromolecules was broken into three kinds of chain compounds: CH 3 CO ZJY;LX,X]RO; R CO ZJY;LX,X] CH 3 O; CH 3 SO 2R and the sulfonic acid groups of original macromolecule were changed into SO 2- 4. |
