Abstract: The present invention discloses a methanol-mediated method for separating an alkaline solution of hemicellulose, and an ethanol-mediated method for separating an alkaline solution of hemicellulose, where methanol/ethanol is added into the alkaline solution in which hemicellulose is dissolved, and stirred thoroughly until the mixture is homogeneous, to destroy the hydrated layer effect formed between the hemicellulose and the alkaline solution through the methanol/ethanol-mediated hydrophobic effect, such that hemicellulose is precipitated from the solution system, and then the mixture is subjected to separation by sedimentation, centrifugation or filtration to obtain a precipitate of hemicellulose and an alkaline solution of methanol/ethanol; and by using the prompting effect of an alkaline condition on evaporation and gasification separation of methanol/ethanol from water, a reduced-pressure distillation (rectification) or gasification membrane is used to separate methanol/ethanol from the alkaline solution, and the obtained alkaline solution and methanol/ethanol are reused for dissolution and separation of hemicellulose. By the complete reuse of the alkaline solution and methanol/ethanol in the method of the present invention, it achieves efficient, clean and economical production of alkaline dissolution and separation of hemicellulose, and the separation and recovery efficiency of the hemicellulose dissolved in the alkaline exceeds 99%.
