Abstract: Disclosed is a method for producing cellulose derivatives wherein cellulose is impregnated with an alkali solution, the impregnated cellulose is selectably pressed out, and the cellulose undergoes a substitution or addition reaction, whereby the cellulose derivative is obtained with a degree of substitution DS. The applied cellulose is an ammonia activated cellulose. The molar ratio of the alkali to the AHG (anhydro glucose unit) in the cellulose at the beginning of the substitution or addition reaction does not exceed twice the valve of the desired DS. For the swelling of cellulose, no excess of alkali is required, which does not react to produce alkali cellulose but only adheres to the cellulose as a loose association product. Reagent consumption in the substitution or addition reaction is lower. Fewer secondary products are formed.
