Abstract

α-Etherification in diol pretreatment quenched lignin intermediate and produced a reactive lignin with hydroxyl tails. Hydroxyl tails increased lignin solubilization without cleavage of β-O-4 ether linkages.

  • Lignin extracts containing variable aromatic rings and side chains are more complex than their original structures.

    “Studies on lignin extraction have demonstrated that the lignin extracts containing variable aromatic rings and side chains are more complex than their original structures [69,135].”

    From Hydrothermal carbonization and liquefaction for sustainable production of hydrochar and aromatics (2021) · cites this paper as [135]

    Section 3.2 reports different aromatic subunit ratios, inter-unit linkages, and a pretreatment-related functional group in the lignin samples. It does not conclude that the extracts are more complex than the original lignin; instead, it describes cleavage of linkages and, in some samples, preservation of structural integrity.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
