A METHOD FOR INCREASING THE REACTIVITY OF LIGNIN |
| 摘要 |
The present invention relates to a method for increasing the reactivity of lignin, wherein the method comprises the following steps: a) forming, under heating at a temperature of 71-94° C., an aqueous dispersion comprising alkali and lignin, wherein the alkali comprises a hydroxide of an alkali metal; and b) heating the dispersion formed in step a) at a temperature of 50-95° C. for producing alkalated lignin. |
