Derivatization Followed by Reductive Cleavage (DFRC Method), a New Method for Lignin Analysis: Protocol for Analysis of DFRC Monomers
Abstract
A new method for selective and efficient cleavage of arylglycerol−β-aryl (β-O-4) ether linkages in lignins is introduced. The acronym “DFRC” relates to the reactions involved, d erivatization f ollowed by r eductive c leavage. Derivatization, accompanied by cell wall solubilization, is accomplished with acetyl bromide in acetic acid; reductive cleavage of resulting β-bromo ethers utilizes zinc in an acidic medium. Following acetylation, degradation monomers (4-acetoxycinnamyl acetates) are quantified by GC, providing data analogous to those from analytical thioacidolysis. Keywords: Acetyl bromide; lignin; β-aryl ether; thioacidolysis; reductive elimination

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.
