Benzyl chloride is an important organic chemical material, widely used in medicine, pesticides, spices and other fields. The following is the manufacturing method of Benzyl Chloride 99.5%:
I. Preparation of raw materials
The main raw materials for manufacturing Benzyl Chloride are benzene and chlorine. In order to ensure the purity and yield of the product, it is necessary to select high-quality raw materials and ensure that the specifications of the raw materials meet the production requirements.
二、Reaction equipment
The production of benzyl chloride requires the use of specialized reaction equipment, generally choose stainless steel reactor. The reaction kettle should have the functions of heating, cooling, stirring and liquid level control to ensure the smooth progress of the reaction.
Three, the production process
1. Charging
Add benzene to the reactor, turn on the stirring, and at the same time through the chlorine gas. During the process of adding, the speed of adding should be controlled to avoid too intense reaction.
2. Reaction
After the dosing is completed, maintain a certain temperature and pressure to let the benzene and chlorine gas fully react. During the reaction, pay close attention to the changes of temperature and pressure, and adjust the process parameters in time.
3. Cooling
When the reaction is completed, stop passing chlorine gas and cool the reaction solution to room temperature. Keep stirring during the cooling process to prevent the material from settling.
4. Separation
Pour the reaction solution into a separatory funnel and let it stand for stratification. The upper layer is benzyl chloride and the lower layer is waste water. Care should be taken to avoid mixing impurities during separation.
5. Refining
The benzyl chloride obtained by separation is refined to remove the impurities in it. The refining method can be by distillation or crystallization.
4. Precautions
1. The production process of benzyl chloride involves chlorine and other toxic and hazardous gases, which requires strict compliance with safety operating procedures to ensure production safety.
2. During the production process, the changes of reaction temperature and pressure should be closely watched, and the process parameters should be adjusted in time to ensure the quality and yield of the product.
3. Care should be taken to avoid mixing impurities during separation and refining to ensure the purity of the product.
In short, the manufacturing method of Benzyl Chloride 99.5% requires strict adherence to the production process and operating procedures to ensure product quality and production safety.
