Sustainable Bio-Based Phenol-Formaldehyde Resoles Using Hydrolytically Depolymerized Kraft Lignin.
In this study bio-based bio-phenol-formaldehyde (BPF) resoles were prepared using hydrolytically depolymerized Kraft lignin (DKL) as bio-phenol to partially substitute phenol. The effects of phenol substitution ratio, weight-average molecular weight (Mw) of DKL and formaldehyde-to-phenol (F/P) ratio were also investigated to find the optimum curing temperature for BPF resoles. The results indic...
متن کاملOxidation and Sulfomethylation of Alkali- Extracted Lignin from Corn Stalk
A lignosulfonate was prepared from alkali-extracted corn stalk lignin (AEL) by oxidation under mild conditions and sulfomethylation. The oxidized AEL exhibited lower molecular weight, narrower molecular weight distribution, and higher phenolic hydroxyl content than AEL, demonstrating that oxidized AEL was more reactive than those before oxidation. The content of sulfonic groups was significantl...
متن کاملFormaldehyde stabilization facilitates lignin monomer production during biomass depolymerization.
Practical, high-yield lignin depolymerization methods could greatly increase biorefinery productivity and profitability. However, development of these methods is limited by the presence of interunit carbon-carbon bonds within native lignin, and further by formation of such linkages during lignin extraction. We report that adding formaldehyde during biomass pretreatment produces a soluble lignin...
متن کاملChanges of Lignin Molecular Structures in a Modification of Kraft Lignin Using Acid Catalyst
The purpose of this study is to modify lignin for better blending with general purpose synthetic polymers. The possible advantages by using this modification would be cost reduction, better physical properties, and biodegradability. In this study, butyrolactone-modified lignin (BLL) and tetrahydrofuran-modified lignin (THFL) were used for aliphatic chain modification of lignin using an acid-cat...
متن کاملCoproduction of ethanol and lignosulfonate from Moso bamboo residues
In the course of utilization of moso bamboo, some fractions are not effectively utilized due to the weakness in mechanical properties. Only a part of these residues are recovered for energy production or made into activated carbon; the remainder are discarded resulting in environment pollution (Mui et al., 2008). As the bamboo residue is a kind of polysaccharides-rich lignocellulosic material, ...
