text: As shown in the evaporative precipitate spectra, the crude lignin separated by RVET could be justified as HSG lignin, which was indicated by signals at 7.49 ppm to 7.76 ppm, 6.59 ppm to 6.78 ppm, and 7.20 ppm, respectively, and the conjugated carbonyl (9.53 ppm to 9.78 ppm) was also found in it.
text: The crude lignin separated by rotary vacuum evaporation treatment (RVET) could be justified as p-hydroxyphenyl-syringyl-guaiacyl (HSG) lignin with conjugated carbonyl functional groups also found in it, while the crude lignin separated by acidification treatment (AT) was mainly composed of S lignin that had β-1, β-5, β-O-4, and β-β bonds.
