Novel and Efficient Diethylene Glycol/H2O Solvent for Lignin Dissolution

open access: yesBioResources, 2016
Novel lignin solvents were developed by adding H2O to diethylene glycol (DEG). The solubility of lignin in the DEG/H2O solvents was determined at 25 °C, and the effect of mass ratio of H2O to DEG on lignin solubility was investigated.

Lignin from Hardwood and Softwood Biomass as a Lubricating Additive to Ethylene Glycol [PDF]

open access: yesMolecules, 2018
Ethylene glycol (EG)-based lubricant was prepared with dissolved organosolv lignin from birch wood (BL) and softwood (SL) biomass. The effects of different lignin types on the rheological, thermal, and tribological properties of the lignin/EG lubricants ...

Lignin‐Based Solid Polymer Electrolytes: Lignin‐Graft‐Poly(ethylene glycol) [PDF]

open access: yesMacromolecular Rapid Communications, 2020
AbstractLignin is an aromatic‐rich biomass polymer that is cheap, abundant, and sustainable. However, its application in the solid electrolyte field is rare due to challenges in well‐defined polymer synthesis. Herein, the synthesis of lignin‐graft‐poly(ethylene glycol) (PEG) and its conductivity test for a solid electrolyte application are demonstrated.

Preparation of flocculant for optimizing glycol lignin manufacturing process by cationization of glycol lignin [PDF]

open access: yesJournal of Wood Science, 2018
Glycol lignin possessing thermoplastic and fusible properties can be a biorefinery platform material; however, glycol lignin is obtained as very small particles in suspension and the low dewatering efficiency is a major difficulty for the mass production.

Lignin Structural Changes During Liquefaction in Acidified Ethylene Glycol [PDF]

open access: yesJournal of Wood Chemistry and Technology, 2012
Beech (Fagus Sylvatica) milled-wood lignin was used as a model substrate in a study of lignin-catalyzed liquefaction in the presence of p-toluene sulfonic acid monohydrate (PTSA) or sulphuric acid as the catalysts. The structural changes that lignin undergoes during the treatment were studied by NMR spectroscopy, FTIR, size-exclusion chromatography ...

Chemical Modification of Plasticized Lignins Using Reactive Extrusion

open access: yesFrontiers in Chemistry, 2019
The reaction of esterification of plasticized Kraft lignin (KL) with succinic and maleic anhydrides using reactive extrusion (REX) was studied in detail. DMSO, glycol and glycerol were found to be efficient plasticizers for lignin. The chemical structure
