Manufacturing Method of Ferric Nitrate
Ferric Nitrate is an important raw material for the production of chemicals, which is widely used in the fields of pharmaceuticals, pigments, catalysts, analytical reagents and so on. This article will introduce the manufacturing method of ferric nitrate.
I. Raw materials and equipment
The main raw materials for manufacturing iron nitrate are nitric acid and iron filings. Nitric acid should be used industrial grade nitric acid, and iron chips should be used pure iron material. The manufacturing process requires the use of equipment such as reactor, stirrer, thermometer and pH meter.
II. Manufacturing steps
1. Dosing
According to a certain proportion of nitric acid and iron filings are added into the reactor, in general, the mass ratio of nitric acid and iron filings is 3:1 to 5:1.
2. Stirring
Start the stirrer and stir the materials in the reactor well to promote the reaction.
3. Reaction
Control the reaction temperature, generally the reaction temperature is between 50-80 ℃, the reaction process need to constantly monitor the pH value, when the pH value reaches a certain value, it means that the reaction has been completed.
4. Filtration
The reaction solution is filtered to remove impurities and unreacted iron filings.
5. Crystallization
The filtered ferric nitrate solution is crystallized to obtain ferric nitrate crystals.
6. Drying
Dry the ferric nitrate crystals to obtain dry ferric nitrate product.
3. Precautions
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 process of dosing, the quality and purity of raw materials should be ensured to avoid the influence on product quality.
3. In the process of filtration and crystallization, attention should be paid to the operation specification and safety to avoid harm to the operation workers and the environment.
4. Product quality standard
The product quality standard of ferric nitrate should be in line with the relevant national standards, including the appearance, content, pH value, heavy metal content and other indicators.
All in all, the manufacturing method of ferric nitrate is not complicated, but it needs to pay attention to the safety and product quality in the manufacturing process, and comply with the relevant regulations and norms to ensure the quality of the products and the safety of the production.
