| titleOfInvention | A kind of refining method of carboxymaltose iron |
| abstract | The invention discloses a method for refining carboxymaltose iron. Carboxymaltose iron aqueous solution is mixed with absolute ethanol for alcohol precipitation. The number of alcohol precipitation is at least 2 times, and the obtained carboxymaltose iron tidal product is washed with absolute ethanol to remove water , and fluidized bed drying to obtain carboxy maltose iron refined products. The uniformity of the material obtained by the invention is very good, and the molecular weight of the material has no obvious change before and after drying, and each index meets the requirements of pharmaceutical raw materials required for the production of carboxymaltose iron injection. The method of the invention is simple, does not require high equipment and technology, is especially suitable for industrial operation, and has great practical significance in actual production. |
