Abstract: The liquefaction of corn stalk in polyhydric alcohol was studied. The results showed that dosage of liquefaction solvent, reaction temperature, reaction time, and catalyst all have significant effect on liquefaction. In the condition of temperature 160 ℃, reaction time 30 min, ratio of solvent to corn stalk 4.5, and ratio of catalyst to liquefaction solvent 3.5%, liquefaction rate would reach 90%, hydroxyl number of liquefied product was 380 mg/g and the viscosity of liquefied product was 353 mPa·s. Finally the relative mechanism of corn stalk liquefaction was investigated by FTIR spectroscopy.

Key words: corn stalk, polyhydric alcohol, liquefaction, hydroxyl number, viscosity
