| titleOfInvention | Cellulose nanofiber and production method thereof |
| abstract | The present invention provides a method for efficiently producing cellulose nanofibers while extracting less modified lignin from woody biomass. A mixing step for producing a mixture 4 comprising a woody biomass raw material 2 and a polycarboxylic acid 3, and a reaction for heating the mixture 4 under a temperature condition within a range of 100 to 200 ° C. to produce a reactant 5. A first washing step in which the reaction product 5 is washed with hot water to obtain a first residue 8; and a second washing step in which the first residue 8 is washed with a solvent to obtain a second residue 11. The lignin remaining in the second residue 11 is decomposed and removed to obtain the cellulose 15 derived from the polycarboxylic acid, and the cellulose 15 derived from the polycarboxylic acid and the aqueous metal salt solution A method for producing cellulose nanofibers, comprising: an organic salt 17 production step for producing salt 17; and a fibrillation step for obtaining cellulose nanofibers 18 in which polycarboxylic acid is derived by stirring organic salt 17 in an aqueous solution. According to the. [Selection] Figure 1 |
