摘      要：Depolymerization of lignin to produce value-added aromatic monomers has attracted increasing attention since these monomers can be used as phenol replacement in production of phenolic *** a one-pot depolymerization of bamboo lignin was investigated to obtain aromatic platforms with low molecular weight using acidic catalyst and *** fractions(1#,2#,and 3#)containing different molecular weight distributions of aromatic compounds could be efficiently extracted using water-organic solvent system via a stepwise fractionation process by gradual removal of *** fractions distribution was found to be primarily dependent on the reaction temperature and *** the temperature was increased from 160°C to 200°C,the yield of fractions containing aromatic products increased significantly from 19.1 wt%to 27 wt%,the same change trend was found by changing the time,and the yield of aromatic products increased from 22.4%to 26.7%with an increase of time from 10 min to 30 *** bioproducts were characterized by using gas chromatography/mass spectrometry(GC-MS),gel permeation chromatography(GPC)and two-dimensional heteronuclear single-quantum coherence(2D HSQC NMR).As evidenced by GC-MS spectra,the three fractions were mainly comprised of phenolic derivatives,and the relative contents of phenolic compounds took up about 80%of the total area of each *** the similar physiochemical properties of the fractions,aromatic platforms could provide a new paradigm of bamboo lignin utilization for renewable energy and value-added biochemicals.
