Modified hydroxyalkyl celluloses and method of preparation

摘要

A method for preparing modified hydroxyalkyl celluloses, particularly hydroxyethyl cellulose which involves adding to the reaction mixture by which hydroxyalkyl celluloses are prepared, a minor amount, in the range of 0.005 to 0.8 mols of methyl chloride or monochloroacetic acid which are additional etherification agents per mol of anydroglucose units.
