A method for quantitative characterization of lignin functional groups |
| abstract |
The invention discloses a quantitative characterization method for lignin functional groups. The method for quantitatively characterizing lignin functional groups includes the following steps: S1 treating the wood sample with benzene alcohol extract and dioxane; S2 placing the S1 treated wood sample in tetrahydrofuran, adding cellulase, and after reaction, The lignin is obtained by elution with the eluent; S3 uses nuclear magnetic resonance to quantitatively analyze the functional groups of the lignin. The method has the advantages of high efficiency, high repeatability and high precision. |
