    摘要: The invention relates to a method for treating lignin, wherein the method comprises the following steps: a) dissolving lignin into an aqueous composition, which contains a compound selected from the class of phenols, while keeping the temperature of the composition at 0-16° C.; and b) allowing the composition to react while keeping the temperature of the composition at 60-100° C. and the pH of the composition at a pH valise of 6-14. The invention relates further to a method for producing a binder composition and to different applications thereof.

    摘要: The present invention relates to a method for fractionating lignin, wherein the method comprises the following steps: (i) dissolving lignin into a mixture containing organic solvent and water; and (ii) ultrafiltrating the mixture formed in step (i) through one or more filtration membranes for producing a predetermined number of lignin fractions, wherein each fraction contains lignin with a molecular weight within a predetermined range. The present invention further relates to a lignin fraction and to the uses thereof.
