Abstract
Process for obtaining water-soluble salts based on carbonic acids of cellulose ethers by transforming the cellulose with a fatty acid of halogens in the presence of alkali, whereby the alkaline cellulose is treated with a fatty acid of halogens, for example monochloroacetic acid in however, not less than 0 25 volumes, preferably 0 45 volumes of halogen fatty acid per 1 volume of cellulose of 90%, and the temperature of the obtained mixture is raised to 40-60º c. Possibly using the heat of reaction when the fatty acid of halogens is bound with the alkaline cellulose and the electrolytes which eventually remain in the pulp are removed by a wash or with mixtures of neutral or acidic alcohols and water or with acidic solutions of water characterized by the fact that the halogen fatty acid is added in anhydrous form.
