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 30 - 70 °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. |
