Abstract

The title process comprises admixing cellulose with an ionic liq. capable of solvating or dissolving at least some of the cellulose, the ionic liq. being a compd. comprised solely of cations and anions (e.g., 1-ethyl-3-methylimidazolium sulfate) and which exists in a liq. state at a temp. at or below 150°, and in which the anions are selected from sulfate, hydrogen sulfate and nitrate; and treating the resulting solvate or soln. with an acid in the presence of water, the acid having a pKa in water of less than 2 at 25°.
