The manufacturing method of dipentene
Dipentene is an important raw material for chemical production, widely used in fields such as spices, pharmaceuticals, pesticides, etc. This article will introduce the manufacturing method of dipentene, including raw material preparation, reaction process, post-treatment, and other links
1、 Raw material preparation: The manufacturing of dipentene requires the preparation of the following raw materials: glutaraldehyde, ethylene, and catalyst. Among them, the ratio of glutaraldehyde to ethylene is 1:1.5-2, and the amount of catalyst is 0.5% -1% of the mass of glutaraldehyde
2、 Reaction process
1 Add glutaraldehyde and catalyst to the reaction vessel and stir evenly
2. Introduce ethylene gas, control the reaction temperature at 80-120 ℃, and the reaction pressure at 0.5-1.5 MPa
During the reaction process, it is necessary to continuously monitor the generation of dipentene and adjust the reaction temperature and pressure as needed
After the reaction is completed, cool the reaction solution to room temperature and separate the crude dipentene
3、 Post processing
1 The crude product of dipentene contains impurities and needs to be refined. The commonly used refining methods include distillation, extraction, crystallization, etc
2. The refined dipentene needs to undergo quality testing to ensure its purity meets the requirements
4、 Notes
1 During the manufacturing process, it is necessary to strictly control the reaction temperature and pressure to ensure a smooth reaction
The selection and dosage of catalysts have a significant impact on the yield and purity of dipentene, and should be selected according to actual conditions
3. In the post-processing process, it is necessary to choose an appropriate refining method based on the properties and impurities of dipentene
In summary, the manufacturing of dipentene requires strict control of the conditions and parameters at each stage to ensure product quality and yield. At the same time, it is necessary to pay attention to safety and environmental issues, and comply with relevant laws, regulations, and standard requirements.
