N2 - Lignin was extracted from pine sawdust by organosolv-extraction using hot-compressed ethanol-water solvent, and bio-based phenol-formaldehyde resol resins were synthesized using the resultant lignin as replacement of phenol at varying ratios. The optimum conditions for extraction of lignin from pine sawdust was 180°C with 50 wt % ethanol solvent, where the lignin yield attained ∼ 26% with a purity of 83%. The resultant lignin under such conditions was an oligomeric material with broad distribution of molecular weights. The as-prepared lignin-phenol resol resins were dark brown viscous liquid solutions whose solid concentrations and viscosities could be adjusted readily by controlling their water contents. This is an abstract of a paper presented at the 8th World Congress of Chemical Engineering (Montreal, Quebec, Canada 8/23-27/2009).
