2,3-Dicarboxy cellulose and partially oxidized 2,3-dicarboxy cellulose were prepared in good yields from the corresponding dialdehyde cellulose obtained by periodate oxidation of cellulose according to a modification of the method described by Hofreiter, Wolff, and Mehltretter [J. Am. Chem. Soc., 79, 6457 (1957)]. The 2,3-dicarboxy cellulose oxidized to nearly 100% oxidation level was completely soluble in water, but the 2,3-dicarboxy cellulose of 70% oxidation level was not. The former 2,3-dicarboxy cellulose took up various metallic ions other than alkali metals to form a precipitate or solid. The metal contents taken up corresponded to the theoretical values calculated as combined in the form of metallic salt of the carboxylic acid group. 2,3-Dicarboxy cellulose combined with metallic ions such as copper, cobalt, and nickel ions gave viscous, gel-like products, which solidified when exposed to air. The properties of products combined with such metallic ions are discussed.
