| titleOfInvention | Iron dextran synthesizing method and its dispersing tablet |
| abstract | The invention discloses a method for synthesizing iron dextran and a dispersible tablet thereof, which comprises the following steps: (1) preparing dextran 20 into dextran hydrolysate, weighing ferric trichloride, and preparing into ferric trichloride solution; (2) adding dextran hydrolysate and ferric trichloride solution into a reaction tank, mixing uniformly, adjusting the pH of the obtained reaction solution to 10-11, heating to a boiling state, and reacting to obtain a complexing solution; (3) and regulating the pH of the obtained complex solution to 6.3-6.8 by using hydrochloric acid solution, and then respectively carrying out rough filtration, intermediate filtration, ultrafiltration and spray drying to obtain the finished product of the iron dextran. The invention provides a method for synthesizing iron dextran and a dispersible tablet thereof, which can improve the iron content and dissolution rate, reduce the impurity content and improve the production efficiency by regulating the pH value before and after a complexing reaction and designing a ceramic ultrafiltration membrane. |
