| 摘 要： | 研究了蔗渣在碳酸乙烯酯中以硫酸为催化剂的快速液化反应。讨论了温度、液固比及催化剂用量等因素对液化反应的影响。对液化产物进行了表征。结果表明蔗渣在碳酸乙烯酯中反应10～20min，残渣率即可降到3％。液化产物为一聚醚酯多元醇体系，羟值为220．330mg／g，可用来制备环氧树脂粘合剂。

| Abstract: | Fast liquefaction of bagasse was conducted in ethylene carbonate in the presence of sulfuric acid as catalyst in order to convert bagasse into product for manufacturing epoxy resin adhesive. Effects of temperature, liquid ratio and catalyst dosage for the liquefaction were investigated. Liquefaction products were characterized. Experiments indicated that bagasse can be liquefied 97 % in approximately 10 - 20 min. The hydroxyl number of the liquefied product is in the range of 220 -330 mg/g. |
