Chemistry of delignification

  author={Josef Gierer},
  journal={Wood Science and Technology},
Delignification processes comprising various pulping and bleaching reactions are reviewed in the light of a general concept dividing these reactions into nucleophilic and electrophilic categories. It is shown by numerous examples that pulping is due to the action of external nucleophilic species attacking electron-deficient centres in carbonyl and conjugated carbonyl (=enone) structures and to the presence of neighbouring nucleophilic groups attacking the β-carbon atom of side chains. On the… CONTINUE READING
