Abstract Lignin is a natural polymer, second only to cellulose in natural reserves. Degradation is one of the ways to achieve
the high-value transformation of lignin. Deep eutectic solvent (DES) thermal degradation of lignin can be used as
an excellent green degradation method. This paper introduces the degradation mechanism and effect of the lactic
acid-choline chloride DES system in dissolving and degrading alkaline lignin, and the final solvent recovery. It can
also be found from the scanning electron microscope (SEM) images that the surface of the degraded solid product
is transformed from smooth to disordered. Fourier transform infrared (FTIR) spectroscopy and… More >
