Abstract
AbstractMolecular modeling is used to explain how grafting various molecules that contain large aromatic structures and different reactive groups onto cellulose dramatically increases the hydrolysis of the glycosidic linkages of cellulose. Hydrolysis is found to increase with the increasing size of the molecule grafted to cellulose, and experiments support this finding. A larger substituent on cellulose increases hydrolysis by causing the hydrolyzed cellulose structure to be more stable compared to hydrolyzed cellulose grafted to a smaller substituent. A larger substituent forms stronger interactions with cellulose and has a greater ability to reduce the mobility of the cleaved cellulose chain to which it is bonded, which allows the cleaved cellulose to form stronger cellulose‐cellulose interactions after hydrolysis. A substituent on the C6 position of cellulose increases hydrolysis to a greater extent than does the same substituent on the C3 or C2 position.magnified image
