Abstract: The liquefaction of bagasse was studied in order to explore a new way for its use£®The conditions of bagasse liquefaction£¬such as liquefaction solvent£¬liquid solid ratio£¬reaction temperature were investigated while the sulfuric acid as a catalyst£®It indicated that the liquefaction efficiency of 96 could be reached in PEG #400£¬and the lignin was liquefied completely£®The liquefied product is a polyether ester polyol and its hydroxyl value is 160mg KOH£¯g¡«300mg KOH£¯g£¬which means that the product can be satisfied as a material for moderate intensity polyurethane foam£®
