Abstract

Salix psammophila was converted to value-added chemicals in the presence of 1-butyl-3-methylimidazolium chloride ([Bmim]Cl) and water by the hydrothermal liquefaction method. [Bmim]Cl acted as both liquefier and catalyst, while water served as both co-solvent and reactant. The optimal reaction parameters for the highest liquefaction yield were determined by an orthogonal experiment. The possibility of application of the recycled [Bmim]Cl was investigated. FT-IR spectra results of the fresh used, the firstly reused, and the secondary reused IL [Bmim]Cl confirmed the high stability of [Bmim]Cl. Moreover, an explanation of the possible liquefaction mechanism for S. psammophila was also provided. This study may provide fundamental data for S. psammophila conversion and application.
