Embodiment 1
[0015] A preparation method of iron sucrose bulk drug, the steps are:
[0016] (1) Iron salt alkalization: dissolve 1-10 parts of iron salt and 1-10 parts of stabilizer in 10-40 parts of distilled water, and add 1-10 parts of 10%-40% alkali solution at 10-30 °C , adjust the pH value to 3-5, filter out the reddish-brown precipitate, and put it into 10-40 parts of distilled water for later use.
[0017] (2) Alkalinization: Dissolve 1-10 parts of sucrose in 10-30 parts of distilled water, add 1-40 parts of 10%-30% lye, and stir at 80°C-120°C for 1-4 hours.
[0018] (3) Complexation: After the reaction in step (2) is completed, add the stock solution obtained in step (1) to the solution obtained in step (2), and react at 80-120° C. for 1-3 hours under stirring. The pH of the system is always kept at 3-6. When the reaction is over, use 10%-30% alkali solution to adjust the pH of the system to 5-8 to complete the complexation.
[0019] (4) Alcohol precipitation: when the complex s...

[0023] A preparation method of iron sucrose bulk drug, the steps are:
[0024] (1) Iron salt alkalization: dissolve 100kg iron salt and 10kg stabilizer in 400kg distilled water, add 100kg of 40% alkali solution at 30°C, adjust the pH value to 5, filter out the reddish-brown precipitate produced, and put Put into 400kg distilled water for subsequent use.
[0025] (2) Alkalinization: Dissolve 100 kg of sucrose in 300 kg of distilled water, add 200 kg of 10% lye, and react with stirring at 80° C. for 4 hours.
[0026] (3) Complexation: After the reaction in step (2) is completed, add the stock solution obtained in step (1) to the solution obtained in step (2), and react at 80° C. for 3 hours under stirring. The pH of the system is always kept at 6. When the reaction is over, adjust the pH of the system to 8 with 30% alkali solution, and the complexation is completed.
[0027] (4) Alcohol precipitation: when the complex solution obtained in step (3) is cooled to room temperature...
Embodiment 3
[0031] A preparation method of iron sucrose bulk drug, characterized in that: the steps of the method are:
[0032] (1) Iron salt basification: dissolve 300kg iron salt and 50kg stabilizer in 600kg distilled water, add 300kg of 40% alkali solution at 20°C, adjust the pH value to 5, filter out the reddish-brown precipitate produced, and put Put into 500kg distilled water for subsequent use.
[0033] (2) Alkalinization: Dissolve 500kg of sucrose in 1000kg of distilled water, add 300kg of 20% lye, and react with stirring at 80°C for 3 hours.
[0034] (3) Complexation: After the reaction in step (2) is completed, add the stock solution obtained in step (1) to the solution obtained in step (2), and react at 100° C. for 3 hours under stirring. The pH of the system is always kept at 5. When the reaction is over, adjust the pH of the system to 7 with 10% alkali solution, and the complexation is completed.
[0035] (4) Alcohol precipitation: when the complex solution obtained in step...
