Walnut　shell　high　boiling　solvent　lignin　(WHL)　was　prepared　by　high　boiling　solvent　method,　and　its　structural　information　could　be　obtained　by　using　chemical　composition　analysis,　infrared　spectroscopy,　and　NMR　spectroscopy.　The　C9-formula　of　WHL,　C9H8.95O　2.37(OCH3)0.72,　was　calculated　by　the　experiment　data.　IR　spectrum　showed　that　the　syringyl　and　guaiacyl　groups　were　clearly　existed　in　WHL.　The　1H-NMR　spectrum　of　WHL　also　indicated　the　aliphatic　and　aromatic　methoxyl　groups　with　relative　intensity　ratio　situated　at　3.5-3.8　and　3.8-4.0　ppm,　respectively.　The　β-O-4　bond　and　β-5　carbon-carbon　linkage　were　found　to　be　the　major　linkages　between　WHL　units　from　the　result　of　13C-NMR　spectrum.　©　2011　IEEE.
