On the structure of lignin in kraft pulping

, 2004
Lignin present in the residual delignification phase is difficult to dissolve and any further pulping leads to an increased loss of pulp strength and yield. In this work, a radical coupling mechanism during kraft pulping is suggested to contribute to the

Hydrotropic Pulping of Miscanthus to Obtain Pulp [PDF]

Journal of Siberian Federal University. Chemistry, 2019
The hydrotropic pulping of crushed straw of Miscanthus sacchariflorus Andersson to produce pulp was studied herein. A concentrated sodium benzoate solution was used as the reagent. Established regularities of the pulping temperature and time effects on delignification quality attributes such as pulp yield and residual lignin content in the pulp.
