FABRICATION OF NEW WATER-SOLUBLE CHITOSAN DERIVATIVES

摘要

A new water-soluble derivative of chitosan - chitosan oligoethylene oxide sulfonate - was synthesized.The ratio and concentration of reacting substances and temperature and duration of the chitosan modification reaction affect the composition and properties of the reaction products.The conditions that ensure a 100% yield of water-soluble chitosan derivatives were determined.Using potentiometric titration and IR spectroscopy,the formation of a new water-soluble chitosan derivative - oligoethylene oxide sulfonate - was confirmed.
