| titleOfInvention | Modified cellulose fine fiber and method for producing the same |
| abstract | The cellulose is esterified and chemically defibrated by impregnating the cellulose with a reactive defibrating solution containing a catalyst containing a base catalyst or an organic acid catalyst, a monobasic carboxylic acid anhydride and an aprotic solvent having a donor number of 26 or more. To produce modified cellulose fine fibers. By this method, the modified cellulose fine fiber having high nanocrystal size, high degree of crystallinity, small fiber shape damage, large aspect ratio, and excellent dispersibility in organic solvents can be easily and without breaking strongly. It can be obtained efficiently. The catalyst may contain pyridines. The monobasic carboxylic acid anhydride may be a C2-4 aliphatic monocarboxylic acid anhydride. The obtained modified cellulose fine fiber is modified with a monobasic carboxylic acid anhydride, has a crystallinity of 70% or more, an average fiber diameter of 20 to 800 nm, and an average fiber length of 1 to 200 μm. Also good. |
