## Abstract The distribution of substituents in a partially acetylated cellulose (DS 2.4) has been determined. __0__‐Acetyl groups were replaced by __0__‐methyl groups by using methylsulphinyl sodium and methyl iodide on a product, in which the original free hydroxyl groups had been protected by re
