Abstract
Polysaccharide ethers are made by treating a solution of the polysaccharide in dimethyl sulphoxide or dimethyl sulphoxide-water mixture with an etherifying reagent. The solution may be made by adding the polysaccharide to the sulphoxide while stirring and heating, adding more sulphoxide if a gel is formed, or by stirring a mixture of the polysaccharide and sulphoxide at room temperature for at least 8 hours. Specified polysaccharides are starch, amylose, xylan, dextrin, arabinogalactans, glucomannans, galactomannans, plant gums, glycogen, dextrans, hemicelluloses, and tamarind kernal mucilage, Examples describe the preparation of methyl, hydroxy-ethyl, hydroxy-propyl, and carboxymethyl ethers of starch.ALSO:Cotton textiles are sized by applying thereto a solution of starch and/or other polysaccharide in dimethyl sulphoxide or dimethyl sulphoxide-water mixture. In an Example, cotton yarns sized at 95 DEG C with 5% solutions of starch in mixtures of dimethyl sulphoxide and water, are dried at 150 DEG C.ALSO:An indicator for use in iodometric titrations comprises a solution of starch or amylose in dimethyl sulphoxide or dimethyl sulphoxidewater mixture. In an Example, 1% solutions of starch and amylose in dimethyl sulphoxide are used in the titration of iodine against sodium thiosulphate.
