  • Patent number: 4599405
    Abstract: A process for the production of iron(III)hydroxide/dextran complexes in which from 2.0 to 2.6 vals of carbonate are slowly added to an acid solution containing a partially depolymerized dextran having an average molecular weight of from 1000 to 10,000 and an iron(III)salt, from 50 to 100 kg of iron ions being used per 100 kg of dextran, after which an alkali metal hydroxide or ammonium hydroxide is added to the solution in such a quantity that, including the carbonate added, approximately 3 vals of anions are added until a pH value of no less about 10.5 is reached, the suspension formed is converted into a solution by heating and the solution is worked up in known manner.The invention also relates to sterile pharmaceutical solutions containing these complexes.
