Description: By pyrolyzing lignin model compounds 1-lV at 315°C, an investigation was carried out with some results. In the pyrolysis of lignin model compound I and 11, 0.47 mol of guaiacol, 0.57 mol of dimethoxyphenol (DMP), and 0.12 and 0.23 mol of dimethoxyaceton ophenone (DMAP) were produced respectively. In the pyrolysis of lignin model compound lll and lV, 0.26 mol of guaiacol, 0.30 mol of DMP, and 0.09 and 0.15 mol of trimethoxy acetonphenone (TMAP) were produced respectively. The results show that pyrolysis mechanism of lignin model compounds were dehydrated at first, and then guaiacol, DMP, DMAP arid TMAP were formed by cleavage of ß-o-4 linkage one after another.

Keywords: Lignin compounds, ß-o-4 linkage, pyrolysis, guaiacyl ring, syringyl ring, veratryl ring, guaiacol
