The manufacturing method
of ferric nitrate
ferric nitrate is an important chemical raw material, widely used in medicine, pigments, catalysts, analytical reagents and other fields. This article will introduce the manufacturing method of ferric nitrate.

1. raw materials and equipment

the main raw materials for the manufacture of ferric nitrate nitric acid and iron filings. Nitric acid shall be industrial grade and iron filings shall be pure iron material. The manufacturing process requires the use of reaction kettle, stirrer, thermometer, pH meter and other equipment.

2. manufacturing steps

1. ingredients

according to a certain proportion of nitric acid and iron into the reaction kettle, under normal circumstances, nitric acid and iron quality ratio of 3:1 to 5:1.

2. Stirring

start the stirrer, the material in the reaction kettle fully stirred evenly, in order to promote the reaction.

3. reaction

control reaction temperature, reaction temperature in general between 50-80 DEG C, the reaction process need to constantly monitor the pH value, when the pH value reaches a certain value, indicating that the reaction has been completed.

4. Filtration

The reaction solution was filtered to remove impurities and unreacted iron filings.

5. Crystallization

The filtered ferric nitrate solution was crystallized to obtain ferric nitrate crystals.

6. Drying

The iron nitrate crystals are dried to obtain a dried iron nitrate product.
Precautions for
3.

1. During the manufacturing process, the reaction temperature and pH value should be strictly controlled to ensure the smooth progress of the reaction and the stability of product quality.

2. In the batching process, the quality and purity of the raw materials should be guaranteed to avoid the impact on product quality.

3. In the process of filtration and crystallization, attention should be paid to operation specifications and safety to avoid harm to operators and the environment.

4. product quality standards

ferric nitrate product quality standards should comply with relevant national standards, including appearance, content, pH, heavy metal content and other indicators.

In short, the manufacturing method of ferric nitrate is not complicated, but it is necessary to pay attention to safety and product quality during the manufacturing process, and comply with relevant laws and regulations to ensure product quality and production safety.
