Abstract

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 pcnt with respect to the amount of kiln-dry material containing lignocellulose.
