摘要： Sulfate ester modified cellulose nanofibers having an average fiber diameter in the range of 1 nm to 500 nm, and having sulfate ester modified hydroxyl groups on surfaces of the cellulose nanofibers. A method of producing cellulose nanofibers that are nanosized, that have a high crystallinity degree, and that have large aspect ratios, the method being a chemical method that does not require any physical pulverization, that is energy-saving, and that can be performed under mild reaction conditions. A method of producing modified cellulose nanofibers including modifying the surfaces of the cellulose nanofibers through esterification or urethanization. A method of producing cellulose nanofibers includes impregnating cellulose with a fibrillation solution containing dimethylsulfoxide, at least one carboxylic acid anhydride selected from acetic anhydride and propionic anhydride, and sulfuric acid to fibrillate the cellulose.

摘要： Fine cellulose fiber has a dispersion with a very high transparency and viscosity. A method is for producing the fine cellulose fiber. In the cellulose fiber, a part of hydroxy groups of cellulose fiber is substituted with a predetermined functional group to introduce an ester of phosphorus-oxo acid, and substituted with a carbamate group to introduce a carbamate. The method for producing fine cellulose fiber includes adding an additive (A) and an additive (B) including at least one of urea and a urea derivative to cellulose fiber, heating the mixture at 100 to 210° C., washing the mixture, and then fibrillating the mixture, the additive (B) being added in an amount of 0.01 to 100 mol based on 1 mol of the additive (A).
