Oxidative Delignification of Flax Fiber
Russian Journal of Applied Chemistry, 2003Oxidative delignification of flax fiber at 98°C was studied. The intermediate material was produced in moderate yield with high degree of delignification. The optimum conditions of the process were determined.

Delignification By Wood-Decay Fungi
Annual Review of Phytopathology, 1991Wood decay fungi are unique because of their capacity to decompose lignified cell walls. A few species are of special interest because they can selectively remove lignin from wood without extensive cellulose degradation. Lignin is a complex, heterogeneous phenylpropanoid structural polymer that occurs throughout the cell wall (71, 112).

The Chemistry of Delignification. A General Concept
Holzforschung, 1982The reactions of lignins during pulping and bleaching are divided into two categories, i.e. nucleophilic additions and displacements, involved in pulping processes, in later phases of lignin-degrading bleaching and in lignin-retaining bleaching, and electrophilic additions and displacements, initiating lignin-degrading bleaching processes.

Hardwood Kraft Delignification
Kraft pulping is a globally significant industrial process whose complexity, stemming from the multi-scale heterogeneity of wood, means a complete understanding of its underlying physicochemical mechanisms remains elusive. This thesis presents research aimed at advancing the fundamental understanding of the kinetics of delignification—the primary step ...openaire +1 more source
Statistic simulation of the delignification process
2019The paper presents a mathematical formalization of regularities during the alkaline treatment of rice straw as one of the stages of oxidation-organosolvent pulping. The purpose of the research is to maximize the yield of technical pulp, to extract minerals and to remove lignin.
