Cellulose photochemistry

Photochemistry of lignocellulosic materials / developed from a symposium sponsored by the Division of Cellulose, Paper, and Textile of the American Chemical Society at the 203rd meeting of the American Chemical Society, San Francisco, California, April 5—10, 1992 Cyril Heitner, J. C. Scaiano, editors.

Cellulose. It has been known for about one hundred years that sunlight degrades cellulose (43), and much work has been done on the photochemistry of cellulose (35,43-450). 

Photochemistry involves the interaction of visible and ultraviolet light with cellulose whereas radiation chemistry involves its interaction with high-energy radiations, such as from y-radiation. Light promotes the deterioration of cellulosic products, particularly cotton fabrics, and certain dyes or other additives greatly accelerate this process known as phototendering. Ionizing radiation is used to sterilize medical and bioproducts many of which are cellulosic. Several authoritative reviews are available [511-514].

The OH radicals resulting from this process are very reactive, i.e. they abstract hydrogens from neighboring molecules and thus initiate further decomposition processes. For detailed information concerning the photochemistry of cellulose, the reader is referred to the relevant literature [17, 46].
