Abstract

Wood consists primarily of carbohydrates (cellulose and some hemicelluloses) and lignin.
In the production of chemical pulps, used in the manufacture of high quality paper, most of the
lignin is removed by reaction with alkaline sulfide. At the elevated temperatures used in
pulping, chemical reactions of lignin give rise to highly colored conjugated aromatic structures
that remain within the wood cell (fiber) walls. The purpose of bleaching is to degrade or
remove these chromophores along with remaining lignin.
