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.

Novel and Efficient Diethylene Glycol/H2O Solvent for Lignin Dissolution
BioResources, 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.
