Valorization of Hydrolysis Lignin for Polyols/Polyurethane Foam (PPT)

摘要

Hydrolysis lignin was successfully liquefied to polyols. Water & ethanol proved better solvent for liquefaction rather than water alone. Polyurethane foam from Hydrolysis lignin was prepared however there density was high with PPG & glycerol. Lower density foam was obtained using Sucrose polyols.
