Abstract
A novel hexonic acid derivative of dextran and a complex thereof with ferric hydroxide which complex is stable and non-toxic and has a high iron content are obtained under carefully controlled conditions by reacting dextran having a molecular weight range between 2000 and 6000 with sodium chlorite; and then reacting with ferric hydroxide to produce the desired complex.
Claims5
A dextran dexonic acid derivative having one or more terminal D-gluconic acid residues obtained by the oxidation of dextran having an average molecular weight of from about 2000 to 6000 with sodium chlorite at a pH of about 2.5-4.5 and at a temperature of about 20.degree.-30.degree. C.
A process for producing a hexonic acid derivative of dextran which comprises oxidizing dextran having a molecular weight between about 2000 and 6000 with sodium chlorite in aqueous solution at a pH of about 2.5-4.5 and at a temperature of about 20.degree.-30.degree. C. and recovering the hexonic acid derivative produced thereby.
