Characterization of Dissolved Lignins in Two-Stage Organosolv Delignification of Wheat Straw

Wheat straw was pre-treated with 0.5 N NaOH at 75°C for 2 h and then post-delignified by 1.0 N H 2 SO 4 catalyzed in ethanol-water (60/40, v/v) system at 75°C for 2 h (Alkaline Pretreatment) or pre-hydrolyzed with 1.0 N H 2 SO 4 for partial release of hemicelluloses at reflux temperature for 2 h and...
