Abstract: Corn straw was liquefied by phenol with sulfuric acid as catalyst.The effects of different phenol/corn straw ratio,sulfuric acid concentration,temperature and time on liquefaction were investigated by orthogonal test.Results showed that the liquid ratio(phenol/corn straw) of 5∶1,reaction temperature of 150 ℃,time of 90 min,and acid concentration of 1.0 mmol/g were ideal conditions for the reaction under which the residue content was 2.44% and the combined phenol was 243.02%.The structure of liquefied corn straw was characterized by FT-IR and aromatic ring was improved to exist.
