Development of an efficient method for chemical recycling plastics and cellulose using supercritical alcohol and organocatalysts

在醋酸碱金属盐存在下，用超临界甲醇处理纤维素进行增溶和分解。产物用甲醇和CHCl_3进行了分离。产物中以甲醇可溶的成分最多，至少含有3种化合物，它们既不是5-HMF等芳香族化合物，也不是葡萄糖。因此，纤维素的这种分解反应应该是一种新的反应，将产生新型的纤维素衍生产品。并对反应条件进行了优化。

Cellulose underwent solubilization and decomposition by treatment with supercritical Me0H in the presence of alkali metal salt of acetate. Products were divided by using MeOH and CHC1_3. MeOH-soluble components, which was the largest fraction of the products, consisted with at least three compounds, which were neither aromatic compounds such as 5-HMF nor glucose. Thus, this decomposition reaction of cellulose should be a new reaction that will give new types of cellulose-derived products. The optimization of the reaction conditions was also examined.
