Method for producing cellulose nanofiber |
| abstract |
(A) The presence of a compound selected from the group consisting of (a1) N-oxyl compounds and (a2) bromides, iodides or mixtures thereof, from a broad-leaved tree-derived raw material having a hemicellulose content of 17% by mass or more (A3) a step of oxidizing using an oxidizing agent, and (B) preparing a dispersion having a concentration of the oxidized cellulose-based raw material obtained in the step A of 0.3% (w / v) or more, Cellulose nanofibers are produced by a method comprising a step of fibrillating and forming nanofibers while dispersing an oxidized cellulose raw material in a dispersion medium. |
