Green Plasticizers from Liquefied Wood - ResearchGate
Green plasticizers were designed from liquefied wood flour, a non-edible biobased waste product. Wood flour was liquefied to low molecular weight polyols by acid catalyzed reaction.
Liquefied biomass derived plasticizer for polylactide
The liquefied wood flour ester (PWF) showed good miscibility with PLA and good plasticization efficiency as shown by differential scanning calorimetry (DSC) and tensile testing. Tensile strain at break increased from a few percent for pure PLA to over 100 and 300% for the materials containing 10 and 30 wt‐% of PWF.

Green plasticizers were designed from liquefied wood flour, a non-edible biobased waste product. Wood flour was liquefied to low molecular weight polyols by acid catalyzed reaction. The resulting polyol mixture, including the remaining liquefaction solvents glycerol and diethylene glycol, was further utilized for the synthesis of low molecular weight ester plasticizers.

- Are green plasticizers made from wood flour?
- Abstract Green plasticizers were designed from liquefied wood flour, a non-edible biobased waste product. Wood flour was liquefied to low molecular weight polyols by acid catalyzed reaction.
- What are liquefied wood based plasticizers?
- The liquefied wood based plasticizers are an attractive alter- native to traditional phthalate plasticizers. Certain varia- tions in the plasticizer structure could be acceptable without significant changes in the material properties, which is an advantage considering the possible variations in biomass.
- How can liquefied biomass derived Plasticizers improve plasticization efficiency?
- The plasticization efficiency of the liquefied biomass derived plasticizers could be further improved by optimizing the liquefaction, esterification and purification processes. The liquefied wood based plasticizers are an attractive alter- native to traditional phthalate plasticizers.
- How are monomeric and oligomeric plasticizers prepared?
- Monomeric (MLWP) and oligomeric (OLWP) plasticizers were prepared by esterification of the polyols by hexanoic acid or a mixture of hexanoic and adipic acid, respectively.
- What is mlwp and olwp plasticizer?
- MLWP, OLWP and traditional dioctyl phthalate (DIOP) plasticizer were blended with poly(vinyl chloride) (PVC) and tensile testing was per- formed to evaluate the plasticizing efficiency of the new plasticizers. In addition PVC blends containing model disaccharide ester, sucrose octaacetate (SOA), were pre- pared and tested.
- Can sugar ester be used as a PVC plasticizer?
- The highest strain at break was, however, obtained by blending PVC with a model disaccharide ester, sucrose octaacetate. This shows that sugar ester have great potential as PVC plasticizers and indirectly indicates that our liquefied wood flour esters contribute to the plasticization of the PVC films.
