Revealing the structure of bamboo lignin obtained by formic acid delignification at different pressure levels
Bamboo was fractionated using formic acid based on a one-step organosolv process under
high pressure (at 145° C for 45 min, 0.3 MPa) and at atmospheric pressure (at 101° C for
120 min), respectively. High-pressure formic acid lignin, atmospheric formic acid lignin and
milled wood lignin of bamboo were subjected to comprehensive structural characterization
using gel permeation chromatography (GPC), Fourier transform infrared (FTIR) and solution-
state NMR techniques (1 H, 13 C, 2D-HSQC, and 31 P-NMR spectroscopies). The results …
