PROCESS FOR PRODUCING CELLULOSE GEL DISPERSION |
摘要 |
A cellulosic material is oxidized with an oxidizing agent in the presence of (1) an N-oxyl compound and (2) a bromide, an iodide or a mixture thereof. The resulting material is subjected to defibration and dispersion treatment to prepare a cellulose nanofiber dispersion liquid. The dispersion liquid thus obtained is acidified so that the cellulose nanofibers are aggregated to form a gelatinous substance. Ultimately, the gelatinous substance is treated mechanically to obtain a cellulose gel dispersion liquid which has low water absorbency and does not tend to swell. |
