Flocculation properties of polyethylene glycol-modified lignin
Separation and Purification Technology, 2020Abstract Polyethylene glycol (PEG)-modified lignin (glycol lignin) can be produced through an acid-catalyzed reaction of Japanese cedar using PEG as a solvolysis reagent. Acid precipitation and the following solid–liquid separation steps are the rate-determining processes for glycol lignin production.

Lignin, one of the most naturally abundant polymers, has been successfully incorporated into ethylene glycol (EG) and poly(ethylene glycol) (PEG) in this work and fortified lubricating properties were achieved in EG/lignin and PEG/lignin. The molecular interaction between lignin and EG (or PEG) has been revealed as hydrogen bonding, which serves as the

Microwave Assisted Preparation of Poly(ethylene) glycol/Lignin Blends for Thermal Energy Storage
, 2021In this research, lignin, an abundant bioresource and a natural polymer, is investigated for its use as the supporting material while poly(ethylene glycol) (PEG) has been used as the working element.

Evidence for the heterogeneity of glycol lignin
Industrial & Engineering Chemistry Research, 1991Glycol and kraft lignins have been fractionated by solvent extraction using a sequence of organic solvents of increasing hydrogen-bonding capability. A comparison between the fractions from both lignins has been made in terms of yield, elemental analysis, Fourier transform infrared spectroscopy, and molecular weight distribution.
