Producing Eucalyptus pellita wood polyol through liquefaction forpolyurethane film production

Depending on the reaction conditions, liquefaction of woody biomass produces a variety of polyol properties. The liquefaction of Eucalyptus pellita (EP) wood powder was studied to optimize the liquefaction conditions for maximum yield. The solvent ratio (PEG/glycerol: 0–25), temperature (140–170 ℃),...
