USE OF SODIUM DITHIONITE IN A CELLULOSE PULPING PROCESS. |
| 摘要 |
The invention relates to a method for producing cellulose from material containing lignocellulose by means of sulfite decomposition or sulfate decomposition in the presence of a salt of dithionous acid, characterized in that the salt of dithionous acid is used in an amount in the range of 0.1 to 4.0 wt% with respect to the amount of kiln-dry material containing lignocellulose. |
