Abstract：

Steam-exploded　lignin　(SEL)　was　separated　from　cornstalk　residue,　which　came　from　steam-exploded　cornstalk　after　enzymatic　hydrolysis.　There　are　two　methods　to　acquire　SEL,　the　alkali　solution　and　the　organic　solvent　method.　SEL　was　analyzed　with　respect　to　the　elementary　composition,　molecular　weight,　IR　spectrum,　and　13C　NMR　spectra.　The　C9-formula　of　SEL　was　calculated　from　the　experiment　data.　According　to　13C　NMR,　SEL　can　be　classified　as　a　＂GSH＂　type　of　lignin,　and　it　is　composed　mainly　of　β-O-4　ether　bonds　together　with　β-5　and　β-1　carbon-carbon　linkages　between　the　lignin　structural　units.　©　2009　Springer　Science+Business　Media,　Inc.
