Document Type and Number:
Japanese Patent JP6656637
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a more efficient lignin flocculant by a lignin production method and a lignin recovery method.SOLUTION: In a lignin flocculant containing cationized lignin in which a lignin part and a cationization agent part are essential: lignin is a lignin derivative obtained by the solvolysis of lignocellulose with at least one digestion solvent selected from among polyethylene glycol, diethylene glycol, ethylene glycol, glycerol and polyglycerol, enzyme lignin obtained by the enzyme saccharification of the lignocellulose or alkali lignin obtained by the alkali digestion of the lignocellulose; and a cationization agent is glycidyltrimethylammonium chloride. The lignin flocculant, a production method of the same and a lignin recovery method using the same are provided.SELECTED DRAWING: None
