Manufacturing method of cuprous chloride
I. Introduction
Copper chloride is an important raw material for the production of chemicals, which is widely used in the fields of organic synthesis, dyestuffs, pharmaceuticals and pesticides. Therefore, it is of great significance to study the manufacturing method of cuprous chloride to improve the production efficiency, reduce the cost and improve the product quality. In this paper, a manufacturing method of cuprous chloride will be introduced, aiming to provide readers with reference.
II. Materials and equipment
1. Materials: copper powder, hydrochloric acid, sodium chloride, sodium hydroxide, ethanol and so on.
2. Equipment: reactor, stirrer, thermometer, condenser, filter, etc.
III. Manufacturing method
1. Pretreatment of copper powder
Add copper powder into ethanol and stir well to remove the oil and oxides on the surface. Then rinse it with distilled water and dry it for spare.
2. Preparation of Cuprous Chloride
Add the pretreated copper powder into the reaction kettle, add a certain amount of hydrochloric acid and sodium chloride, and stir well. Then heat the reaction kettle, control the temperature within a certain range, and after reacting for a certain time, stop heating and cool to room temperature.
3. Post-treatment
The reaction solution was filtered to remove unreacted copper powder and impurities to obtain cuprous chloride solution. The solution was concentrated to a certain concentration and crystallized by cooling to obtain cuprous chloride crystals. The crystals are washed with ethanol and dried to obtain the copper chloride product with high purity.
4. Precautions
1. The pretreatment of copper powder should be thorough so as not to affect the product quality.
2. Control the reaction temperature and time, so as not to produce by-products or affect the purity of the product.
3. Keep the environment clean during the post-treatment process to avoid impurities contaminating the product.
5. Conclusion
This paper introduces a manufacturing method of cuprous chloride, which is simple in operation, easy to obtain raw materials and has high product quality. By controlling the reaction conditions and post-treatment process, the product purity and yield can be further improved. It provides reference for readers.
