different methods, including ball mill grinding, steam explosion, alkaline treatment, phosphoric acid, and ionic liquid (IL) dissolution/reprecipitation have been systematically investigated. The chitin structures were thoroughly investigated by using a series of analytical techniques, and the reactivity after each treatment was evaluated in dehydration and liquefaction reactions. The parallel studies enable
系统研究了使用球磨机研磨,蒸汽爆炸,碱处理,磷酸和离子液体(IL)溶解/再沉淀等不同方法进行的甲壳质处理。通过使用一系列分析技术彻底研究了几丁质结构,并在脱水和液化反应中评估了每种处理后的反应性。平行研究能够对这些方法进行直接比较,并有助于建立构效关系。干法球磨是最有效的方法,晶体尺寸和氢键网络是提高反应性的两个关键因素。值得注意的是,几丁质脱水产生的3-acetamido-5-acetylfuran(3A5AF)的产量增加到最高水平(28。
