| Abstract: | The liquefaction technology of bamboo powder was studied by taking dolyethylene glycol 400 as the solvent. The results showed that the liquefaction rate could reach 98.3% when the liquid-solid ratio was 3： 1, the dosage of concentrated sulphuric acid was 6%, the bamboo powder was input gradually and the reaction took 2 h at 150℃. Under the above condition, the hydroxyl value of the liquefied polyol ranged from 152 mg KOI-I/g to 244 mg KOH/g, which was suitable for the preparation of hemi-horniness foam. |
