Under the action of alkali, lignin is hydrolyzed to a certain extent, which increases its solubility, and the lignin is extracted and separated by precipitation to obtain lignin called alkali lignin. Alkali lignin precipitation can also be obtained by neutralizing alkaline pulping waste liquor with flue gas (CO2) or acid treatment.
The molecular weight of lignin in wood is more than 10 000, while the molecular weight of alkali lignin is about 1000-2000.
