The manufacturing method
of cuprous chloride
1. Introduction

Cuprous chloride is an important chemical production raw material, widely used in organic synthesis, dyes, medicine, pesticides and other fields. Therefore, it is of great significance to study the manufacturing method of cuprous chloride for improving production efficiency, reducing cost and improving product quality. This article will introduce a manufacturing method of cuprous chloride, aiming to provide readers with reference.

2. materials and equipment

1. Materials: copper powder, hydrochloric acid, sodium chloride, sodium hydroxide, ethanol, etc.
2. Equipment: reaction kettle, stirrer, thermometer, condenser, filter, etc.

3. Manufacturing Method

1. Pretreatment
of Copper Powder
Copper powder is added into ethanol, and stirred evenly to remove oil stains and oxides on the surface. Then rinse with distilled water, dry standby.

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 in a certain range, after a certain time, stop heating, cooling to room temperature.

3. Post-treatment

The reaction solution was filtered to remove unreacted copper powder and impurities to obtain a cuprous chloride solution. The solution was concentrated to a certain concentration, cooled and crystallized to obtain cuprous chloride crystals. The crystal is washed with ethanol and dried to obtain a high purity cuprous chloride product.
Precautions for
4.

1. The pretreatment of copper powder should be thorough, so as not to affect product quality.
2. Control the reaction temperature and time to avoid by-products or affect product purity.
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 to operate, easy to obtain raw materials and high product quality. By controlling the reaction conditions and post-treatment process, the product purity and yield can be further improved. Provide reference for readers.
