Lignin, a component of lignocellulosic biomass, is abundant and is produced extensively as a waste product of the Kraft pulping process, lignin obtained from this process is called Kraft lignin (KL).

Lignin’s three-dimensional structure composed of aromatic alcohols (monolignols) makes it a potential source of renewable aromatic chemicals or bio-oil, if depolymerized. Hence, lignin from pulping industry could also serve as a feedstock for lignin valorization for production of low value sulfonates and high-value products (Upton and Kasko, ).

estimated that about 2, ton of Kraft lignin was produced and could be used for production various aromatics. However, the high cost of alkali and neutralization of.

The chemistry of lignin polymerization was studied in the past. Insights into the rheological behavior of the lignin polymerization system would provide crucial information required for tailoring lignin polymers with desired properties.

The in-situ rheological attributes of lignin polymerization with a cationic monomer, [2-(methacryloyloxy)ethyl] trimethylammonium chloride (METAC), were. Focusing exclusively on the chemistry of wood, wood components, and wood products, this high-quality journal covers the latest advances in areas such as the chemistry of pulping, lignin, cellulose.

Lignin nanosizing has received much interest as it offers new potential for value-added applications of the currently under-utilized lignin biopolymers. However, conventional lignin nanosizing technologies often rely on the use of large amounts of toxic organic solvents, and a.

The β-aryl ether (β-O-4) linkage is the ubiquitous interunit linkages in native lignin, the content of which is reported to range from ca. 43% (softwood) to ca. 65% (hardwood). 12 Hence, it is the main target structure for cracking during lignin depolymerization.

Lignin is a class of complex organic polymers that form key structural materials in the support tissues of vascular plants and some algae. Lignins are particularly important in the formation of cell walls, especially in wood and bark, because they lend rigidity and do not rot ally, lignins are cross-linked phenolic polymers.

According to the ATR spectra shown in Fig. 3, only the functional groups of the cellulose component were revealed in the spectra of the unprinted décor papers, which accentuated the fact that the pulp (alpha pulp) used for making décor paper is essentially devoid of hemicelluloses and lignin, and was in good agreement with the reports from.

Lignin is the wood component most sensitive to UV radiation, which produces degradation of lignin followed by photo-oxidative effects. Modification of lignin results mostly in yellowing due to the formation of quinones, quinone methides, and stilbenes (Fengel and Wegener ; Müller et al. However, extractives contribute to both the.
