| titleOfInvention | Method for producing high purity lignin |
| abstract | An object of the present invention is to provide a method for producing high-purity lignin from black liquor during pulp production in a simple process and without producing a large amount of drainage. Ion exchange of lignin, particularly herbaceous lignin, in black liquor containing black liquor during pulp production, preferably soda lignin obtained by treating a raw material plant with a soda process, using an ion exchange resin. To obtain high-purity lignin. At this time, the molar ratio (A / B) of the functional group (A) in the ion exchange resin and sodium (B) in the black liquor is 1 or more, and the pH after the desalting treatment is 1 to 4, and the black The concentration of lignin in the liquid is preferably 16% by mass or less based on the total amount of black liquor. The ion exchange resin is a cation exchange resin that adsorbs Na + by desalting. [Selection figure] None |
