The manufacturing method
of isobutyraldehyde
isobutyraldehyde is an important organic chemical raw material, which is widely used in medicine, pesticide, plastic, rubber, spice and other fields. This article will introduce the manufacturing method of isobutyraldehyde, including raw materials, process flow, operation points, safety and environmental protection.

1. raw material

The raw materials for the manufacture of isobutyraldehyde are mainly isobutanol and oxygen. Among them, isobutanol can be obtained through petrochemical raw material cracking, fermentation and other ways, and oxygen can be obtained through air separation and other ways.

2. Process
The manufacturing process of
isobutyraldehyde mainly adopts oxidation method, and its process flow is as follows:

1. Isobutanol and catalyst are added into the reactor, and oxygen is introduced for oxidation reaction.
2. The isobutyraldehyde and water vapor produced by the reaction are condensed by the condenser and then enter the separator for separation.
3. Isobutyraldehyde is discharged from the upper part of the separator for further refining treatment; water vapor is discharged from the lower part and can be recycled.

3. operating points

1. control the reaction temperature and pressure to ensure a smooth reaction.
2. Select the appropriate catalyst to improve the reaction rate and selectivity.
3. Regularly carry out equipment maintenance and overhaul to ensure the normal operation of the equipment.

4. safety and environmental protection

1. In the production process, strictly abide by the safety operation procedures to ensure the safety of employees and equipment.
2. Effective treatment of waste gas, waste water and other pollutants to meet environmental requirements before discharge.
3. Strengthen production management, reduce running, running, dripping, leakage and other phenomena in the production process, and improve resource utilization efficiency.

In short, the manufacturing method of isobutyraldehyde involves many aspects and requirements, which need to be fully considered and implemented in the actual production process to ensure product quality and production safety and environmental protection.
