The Nature and Reactions of Lignin--a New Paradigm.

The Nature and Reactions of Lignin--A New Paradigm

by K.G. Forss and K.E. Fremer

Lignin, which represents nearly one-third of plant tissues, is a key participant in the formation and transformation of organic material in the biosphere. Its reactions play a vital role in the manufacture of paper. It is believed that lignin is a single polymer formed through random reactions outside genetic control and that it cannot be described by an exact formula. The authors show that lignin is not one polymer but a group of lignins. In the conifer Norway spruce a polymer, which they call glycolignin, constitutes some 85 percent of the lignins. Glycolignin is described as an ordered polymer. The development of a three-dimensional formula is described step by step. This formula enables glycolignin reactions (including color formation) to be described quantitatively and kinetically. 2003. Published by the authors. 555 pages, hard cover.
