摘要：

Three different ionic liquids (IL), 1-butyl-3-methylimidazolium chloride ([BMIM]Cl), 1-ethyl-3-methylimidazolium chloride ([EMIM]Cl), and 1-butyl-3-methylpyridinium chloride ([BMP]Cl), were used as reaction media in hydrolysis reaction of poplar seed floss (as cellulose material) with cellulase. Hydrolysis kinetics of the IL-treated cellulose material was significantly enhanced. The initial hydrolysis rates for IL-treated cellulose material were greater than that of non-treated cellulose material. This behavior seems to be due to synergetic effects of ionic liquid and cellulase upon cellulose material. Structural modifications were investigated by Fourier transform-infrared spectroscopy (FT-IR). Thermal properties of poplar seeds floss were also evaluated by TG-DTG-DSC simultaneous analysis.
