Sulfur, bond strengths crystalline

In acidic conditions, glycosidic bonds are cleaved in the cellulose structure. The rate of this reaction is controlled by the crystallinity of the cellulose and the temperature of the system (3, 5, 6). The resultant hydrolyzed cellulose has a shorter chain length than the original polymer, which greatly decreases the strength of the wood (7). Hackney (8) noted embrittlement and discoloration of sulfur dioxide exposed cellulose fibers. Such acid hydrolysis experiments have been conducted in aqueous systems, with the degradation rate dependent on the difiiision characteristics of the acidic solution into the wood structure. Because museum artifacts will not normally... [Pg.401]
