Glucose production from cellulose using ionic liquids

开发了一种以纤维素为原料生产葡萄糖的新方法。在疏水性离子液体中，纤维素、盐酸和氯化锂的混合物能有效地使纤维素水解，从而使葡萄糖的得率超过40%。在此条件下实现了葡萄糖的选择性生成。分离的葡萄糖没有受到离子液体的污染，离子液体可能会抑制葡萄糖发酵生产乙醇。离子液体的回收率在99%以上，并用于多次重复使用而不损失效率。葡萄糖的产率随着氯化锂加入量的增加而增加。

A new method to produce glucose from cellulose was developed. A mixture of cellulose, hydrochloric acid, and lithium chloride in hydrophobic ionic liquids provided efficient hydrolysis of cellulose to give glucose more than 40% yield. A selective formation of glucose was achieved under these conditions. Glucose was isolated without contamination of ionic liquids, which potentially inhibit fermentation of glucose to produce ethanol. The ionic liquids were recovered in more than 99% and used for the hydrolysis for several iterations without loss of efficiency. The yield of glucose increased as the amounts of lithium chloride increased.
