Reaction Steps
Sodium cellulose sulfate (SCS) is a long known, water-soluble polymer of the sulfuric acid half ester of cellulose. SCS is formed by the esterification of the hydroxyl groups of the cellulose with a sulfating agent, e.g. sulfuric acid anhydride, sulfuric acid or their derivatives followed by the conversion of the acidified half ester into a neutral sodium salt.
