摘要：
There is described a method of fractionating a biomass material comprising: (i) blending the biomass material with an acid catalyst to form a slurry； (ii) mixing the slurry with an organosolv reagent optionally under an inert atmosphere to form a pre-treatment mix； (iii) subjecting the pre-treatment mix to sonication； (iv) optionally heating the product of step (iii) in an autoclave under pressure； (v) separating the solid and liquid components of the fractionation mix； (vi) optionally washing the solid； (vii) optionally drying the solid component； (viii) separating the liquid component into organic and aqueous components； and (ix) isolating lignin from the organic component and/or isolating hemi- cellulose from the aqueous component.
