Behavior of Lignin during alkaline Sulfite-Quinone Cooking

TL;DR: The sulfite-quinone cooking has been investigated as an alternative to the kraft process in terms of delignification, pulp yields, and pulp qualities as discussed by the authors, and the properties of lignin in this cooking have not been clarified.

Sodium Sulfite-Formaldehyde-Quinone Cooking of Softwood

TL;DR: In this article, a new cooking process with sodium sulfite, formaldehyde, and a quinone compound (1, 4-dihydro-9, 10-Dihydroxyanthracene sodium salt: DDA) was devised in order to produce soft wood semichemical and chemical pulps which are superior to neutral sulfite and kraft pulps, respectively.
