Acidic Solvolysis of Softwood in Recycled Polyethylene Glycol System
BioResources, 2016 The acidic solvolysis of lignocellulose using a glycol solvent such as polyethylene glycol (PEG) is a promising process for separating its components and producing a valuable lignin product that can be used as thermoplastic and fusible materials.

Lignin studies of transgenic Norway spruce [PDF]
, 2006 An attractive objective in tree breeding is to reduce the content of lignin, or increase its extractability, to favor delignification during pulping. This study investigates the potential for lignin alterations in Norway spruce (Picea abies [L.] Karst ...

Lignin Valorization via Acidolysis with Ethylene Glycol Stabilization [PDF]
, 2021 This thesis describes several aspects of lignin acidolysis with ethylene glycol stabilization and possible applications of the obtained monomers. An efficient strategy was developed to convert native lignin in lignocellulose to new lignin-derived platform chemicals (G/S-C2-acetals), a set of monomers that is not accessible via other lignin ...

Ethylene Glycol from Lignocellulosic Biomass: Impact of Lignin on Catalytic Hydrogenolysis [PDF]
Industrial & Engineering Chemistry Research, 2021 Short polyols, such as ethylene glycol (EG), are a popular target of catalytic hydrogenolysis of saccharides. However, studies on the use of untreated or pretreated lignocellulosic biomass as feedstock for polyol production are scarce. In this work, we have studied the impact of lignin on the catalytic hydrogenolysis of different biomass samples ...

Chemical Modification of Plasticized Lignins Using Reactive Extrusion
Frontiers 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
