Oxidative conversion of lignin isolated from wheat straw into aromatic compound catalyzed by NaOH/NaAlO.

Lignin was isolated from wheat straw via organosolv process and further transferred to monophenolic compounds via oxidative conversion. Wheat straw lignin (WSL) with purity at 91.4 wt% was acquired in the presence of heterogeneous and recyclable catalyst of Amberlyst-45.
