Abstract

The invention relates to a method and device for eliminating sodium chloride in the aqueous solution for the complex of ferrodextran, which is characterized in that: the ferrodextran is prepared with dextran and ferric trichloride. The sodium chloride in the ferrodextran is eliminated with an electrodialysis film, that is, eliminating the sodium chloride of the solvent by electrodialysis process in the ferrodextran complex solvent with iron content is more than or equal to 40mg / ml, sodium chloride content is more than or equal to 5.0 per cent wt and viscosity of 3.0mpa is multiplied by s (20 DEG C.) under the temperature of 10 to 90 DEG C. Compared with the technique of eliminating sodium chloride with alcohol precipitation, the invention prevents the safety hazard from flammable and combustible alcohol and reduces the production cost.

Description

technical field [0001] The invention relates to a method and device for removing impurities in the process of producing iron dextran complex, in particular to a method and device for removing sodium chloride in an aqueous solution of iron dextran complex. Background technique [0002] Iron dextran is an iron supplement for humans and animals. Iron dextran can be used to treat iron deficiency anemia in humans or animals by oral or injection. Iron dextran is a macromolecular complex, which is obtained by degrading dextran (weight average molecular weight about 20,000) under alkaline conditions, then neutralizing it with acid, and performing a complex reaction with ferric chloride. The stock solution of iron dextran complex contains a large amount of inorganic salt-sodium chloride, and its weight percentage is generally greater than 10%. The iron dextran injection requires that the iron dextran solution sodium chloride has a weight percent concentration of less than 2%, so the...
