Explosion risk and preventive measures of n-butyl acrylate mixed with oxidant?

Butyl acrylate and oxidant mixed explosion risk and preventive measures

In the process of chemical production and storage, the mixing operation of n-butyl acrylate and oxidant may have explosion risk. This paper will analyze this problem in depth and discuss the causes of explosion risk and its preventive measures to ensure production safety.

1. of n-butyl acrylate and oxidant mixed explosion risk analysis

n-Butyl acrylate is a flammable liquid with a low flash point and high volatility, which easily forms an explosive mixture in air. When it comes into contact with an oxidizing agent such as hydrogen peroxide, peroxyformic acid, etc., a violent oxidation reaction may occur, generating a large amount of heat, gas, and pressure, thereby causing an explosion.

Reactivity is the main influencing factor. N-butyl acrylate is chemically active and easily reacts with oxidants, especially in the presence of high temperature, light or catalyst, the reaction rate will increase significantly, resulting in increased risk. Conditions such as concentration, temperature and container material also increase the risk of explosion.

2. Explosion Risk Precautions

1. Operation specification: strictly follow the chemical operation procedures, carry out mixed operation in a well-ventilated environment, avoid high temperature and open fire. Operators are required to wear protective equipment, such as gas masks and gloves, to ensure personal safety.

2. Environmental control: Reduce the risk of explosion by dilution, use of inert gas protection and control of reaction temperature. Dilution can reduce the concentration of n-butyl acrylate in the air, and inert gas can isolate oxygen to prevent the occurrence of oxidation reaction.

3. Equipment safety: select pressure-resistant and corrosion-resistant equipment, and install explosion-proof devices. Ensure that the equipment is in good running condition, check and maintain regularly to avoid safety accidents caused by equipment failure.

3. case analysis and experience summary

Actual cases show that a number of n-butyl acrylate-related explosion accidents are caused by improper operation or equipment problems. Through the analysis of these cases, we can learn lessons and further improve the safety operation procedures. For example, during storage, it is necessary to ensure that the container is sealed to avoid contact with oxidants; during transportation, it is necessary to load and unload lightly to prevent packaging damage.

4. Conclusion

The explosion risk of n-butyl acrylate mixed with oxidant cannot be ignored, and effective preventive measures must be taken. Through strict operation specifications, environmental control and equipment safety design, the explosion risk can be significantly reduced to ensure the smooth progress of chemical production. Chemical practitioners should continue to pay attention to such safety issues, continuously improve safety awareness and emergency response capabilities, and jointly build a safe production environment.
