FIELD: chemistry.
SUBSTANCE: in accordance with the claimed method a lignocellulose material is brought in contact with the conjugated acid, formed by a strong organic base and a weaker acid, under the conditions, which lead to at least the partial dissolution of the cellulose components of the lignocellulose material.
EFFECT: method makes it possible to extract a part of a dissolved portion of the lignocellulose material by means of the partial dissociation of the conjugated acid, the method makes it possible to extract a part of the dissociated organic base and acid, obtain the conjugated acid from an extracted base and acid and supply it in recycle to the first stages of the method.
