In the present examination, the thermochemical behavior of the lignin extracted from willow (Salix matsudana cv. Zhuliu) by deep eutectic solvents (DES) treatment (DES-lignin) with varied times were investigated with the techniques of thermogravimetric analyzer, in situ diffuse reflectance infrared pyrolysis (in situ-FTIR), and pyrolysis-gas chromatography/mass spectrometry. The results showed that thermal degradation of DES-lignin mainly occurred at 185-470 degrees C with two maximum weight loss peaks at 265 degrees C and 380 degrees C respectively, and the solid residue was 40% when terminated at 800 degrees C. The identified cluster of aromatics from in situ-FTIR was detected earlier and stronger than those of small molecular gases, suggesting cleavage of lignin intermolecular linkages dominated the initial pyrolysis process. The DES-lignin was sensitive to pyrolysis to produce aromatics. The total phenols yield from DES-lignin pyrolysis reached a maxima of 95.1% at 450 degrees C, among which phenol and guaiacol accounted for the largest proportion, i.e. 20.8% and 24.2% respectively. In addition, product distribution was remarkably affected by pyrolysis temperature and the DES treatment time used for lignin isolation.
