Journal ArticleDOI
Mild hydrogenolysis of in-situ and isolated Pinus radiata lignins
TL;DR: The Pd/C-catalysed hydrogenolysis of in-situ and isolated lignins from Pinus radiata wood was investigated to gain a more complete understanding of the factors affecting yield and composition of the Hydrogenolysis products.
Journal ArticleDOI
Biobased Epoxy Resins from Deconstructed Native Softwood Lignin
TL;DR: Results indicate lignin hydrogenolysis products have potential as sustainable biobased polyols in the synthesis of high performance epoxy resins.
Journal ArticleDOI
Solvent extraction as a means of preparing homogeneous lignin fractions
Jarmo Ropponen,Lea Räsänen,Stella Rovio,Taina Ohra-aho,Tiina Liitiä,Hannu Mikkonen,Daniel J. van de Pas,Tarja Tamminen +7 more
TL;DR: In this paper, a sequential extraction method was applied to lignins from hardwood and softwood isolated by kraft and VTT organosolv processes, and solvent extraction was found to fractionate lignin according to the molecular weight.
Journal ArticleDOI
Thermosetting Polymers from Lignin Model Compounds and Depolymerized Lignins
Elias Feghali,Kirk M. Torr,Daniel J. van de Pas,Pablo Ortiz,Karolien Vanbroekhoven,Walter Eevers,Walter Eevers,Richard Vendamme +7 more
TL;DR: Particular emphasis is given to epoxy resins, polyurethanes and phenol-formaldehyde resins as this is where the research shows the greatest overlap between the model compounds and bio-oils.
Journal ArticleDOI
Characterization of fractionated lignins polymerized by fungal laccases
Daniel J. van de Pas,Aynsley C. Hickson,Lloyd Donaldson,Gareth Lloyd-Jones,Tarja Tamminen,Alan Fernyhough,Maija-Liisa Mattinen +6 more
TL;DR: In this article, commercial Alcell, birch organosolv lignins, and steam-exploded pine and eucalypt lignin were sequentially fractionated by ether, ether/acetone 4:1 (v:v), and acetone.
