    • A method in which a lignophenol derivative is recovered from a lignocellulosic substance through a treatment with a phenol derivative and an acid, and a sugar can be easily and efficiently recovered from the acid/sugar solution obtained simultaneously therewith and can be used easily and efficiently. The method of separating and recovering an acid/sugar solution and a lignophenol derivative is characterized by adding a liquid reaction mixture comprising a lignocellulosic substance, a phenol derivative, and an acid to water, the amount of which is 0.5 to 6 times by volume the amount of the liquid mixture, keeping the resultant mixture in a stationary state or gently stirred state to coagulate the lignophenol derivative generated as a solid phase, and then subjecting this mixture to solid-liquid separation to thereby separate and recover the lignophenol derivative as a solid phase and an acid/sugar mixture as a liquid phase.
    • 通过苯酚衍生物和酸的处理从木质纤维素物质中回收木质素衍生物的方法,并且可以从与其同时获得的酸/糖溶液中容易且有效地回收,并且可以容易且有效地使用。 分离和回收酸/糖溶液和木酚酚衍生物的方法的特征在于将含有木质纤维素物质,酚衍生物和酸的液体反应混合物加入水中,其量为水的0.5至6倍 液体混合物的量,将所得混合物保持在静止状态或温和搅拌状态以凝固作为固相产生的木酚酚衍生物,然后将该混合物进行固液分离,从而分离和回收作为固体的木酚酚衍生物 相和作为液相的酸/糖混合物。
