Preparation of multinuclear ferric-saccharidic complexes |
| abstract |
The invention discloses a process for preparing multinuclear ferric hydroxide-saccharidic complexes, comprising: titrating an aqueous solution of iron salt with an aqueous solution of alkali to a final pH of 6~8 under 5~20 , collecting the multinuclear ferric hydroxide from the reaction product by conventional method; maintaining a reaction mixture of multinuclear ferric hydroxide, saccharides and solution of alkali for 10~40 hours under a temperature of 106~125 and pH being 10~12, and obtaining the crude product having an isoelectric point of 4.4~5.3 and a weight average molecular weight of 20000~100000 Daltons, and then collecting the multinuclear ferric hydroxide-saccharidic complexes from the crude product. The process can control the molecular weight of the multinuclear ferric hydroxide-saccharidic complexes exactly while not influencing other characteristics of the product such as content of saccharides or isoelectric point etc, and which is simple and readily applicable in industry. |
