| Research Abstract |
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.
