| titleOfInvention | Sulfate-esterified fibrous cellulose, composition, sheet and method for producing sulfate-esterified fibrous cellulose |
| abstract | PROBLEM TO BE SOLVED: To suppress thermal decomposition of fine fibrous cellulose which has been sulfate-esterified. The present invention relates to a composition containing a carbamide group and having a fiber width of 1000 nm or less, a sulfate-esterified fibrous cellulose, a sulfate-esterified fibrous cellulose, and a sheet containing a sulfate-esterified fibrous cellulose. Further, the present invention is a step (a) of mixing a cellulose raw material with an aqueous solution containing sulfuric acid and / or sulfuric acid amide, and urea and / or a urea derivative, and heating the cellulose raw material at 100 ° C. or higher until the water content is substantially eliminated. It also relates to a method for producing sulfate-esterified fibrous cellulose, which comprises a step (b) of refining the cellulose raw material obtained in the step (a). [Selection diagram] None |
