Dextran hexonic acid derivative, ferric hydroxide complex and method manufacture thereof

摘要

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.
