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 reaction with methyl vinyl ether. The methylated sugars obtained on acid hydrolysis of this product were converted into alditol acetates and analyzed by GLC‐mass spectrometry.

## Abstract A new process of decrystallization of cellulosic materials^8^ is described. The process involves the preparation of alkali‐cellulose and an interaction between alkali‐cellulose and acetic anhydride. The decrystallized products thus obtained are partially acetylated and are designated as
