  • STUDY ON ION EXCHANGE REACTION OF OXYCELLULOSE

抄録

Two type of oxycellulose films (20μ in thickness) containing uronic and nonuronic carboxyl groups were reacted with various metallic salt solutions, and the effects of pH, of the concentration of the solution and also of the solvent added on ion-exchange reaction were studied by infrared spectrometry.<br>1) For analyzing the carboxyl group in cellulose spectrometrically, it is obviously preferable to determine the absorbance due to ν C=O of the samples after ion exchange.<br>2) Both uronic and nonuronic carboxyl groups in cellulose behaved as a weakly acidic cationexchanger in the reaction with various metallic salts.<br>3) The effects of the cations and anions of various metallic salts on ion exchange capacity were as follows;<br>4) Uronic and nonuronic carboxyl groups in cellulose were separated from each other by the exchange reaction with alcoholic or acetonic aqueous solution of aluminium nitrate.<br>* Study of Oxycellulose Part 10
