Abstract:By the method of high boiling solvent (HBS), HBS-lignin has been separated from pine-nut hull with 1,4-butanediol solution as solvent, and characterized by GPC, IR, 1HNMR and TG. The optimal conditions are described as: the ratio of solid raw material to solvent (g:mL) in 1:12, the amount of catalyst in 6%, the reaction time for 2 hrs, reaction temperature at 200°C, and 90% of 1,4-butanediol as the solvent, and the yield of lignin up to 70%. The hydroxyl value of obtained HBS-lignin is about 197.2mgKOH/g. Furthermore, the HBS-lignin replaces the partial PEG400 to employ the synthesis of lignin-PEG-PAPI. The experimental results indicate that mechanical properties and solvent resistance of lignin-PEG-PAPI are apparently improved with comparison to the PEG-PAPI.
