Contributions to Tobacco and Nicotine Research, 2022 High lignin content of tobacco stem has been addressed as a drawback for its utilization on manufacture of reconstituted tobacco sheet. Therefore, the solvothermal method using ethylene glycol was investigated for the removal of lignin from tobacco stem.

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

Angewandte Chemie, EarlyView.A photocatalytic approach for efficient one‐pot direct lignin depolymerization and subsequent cross‐coupling with alcohols for the production of unsymmetrical aromatic diols has been demonstrated. ABSTRACT Conversion of lignin into chemical products typically involves two separate steps, such as depolymerization and subsequent upgrading of monomers ...
