What is the explosion limit range of n-butyl acrylate?

Butyl acrylate (Butyl Acrylate) is a common acrylate compound, which is widely used in coatings, adhesives, plastics and other fields. Due to its possible explosion risk during industrial production and storage, understanding the explosion limit range of n-butyl acrylate is essential for safe production. This paper will analyze the explosion limit range of n-butyl acrylate and its related safety knowledge in detail.

1. PROPERTIES OF N-BUTYL ACRYLATE

n-Butyl acrylate is a colorless liquid with a slight odor. Its chemical formula is C₂ H₂ O₂ and its molecular weight is 130.15. n-Butyl acrylate is flammable and has a certain volatility in the air, which makes it a risk of explosion during storage and use.

2. the explosion limit range

The explosion limit refers to the concentration range of combustible gas or vapor in the air that can explode when it encounters a fire source. The explosion limit range of n-butyl acrylate is a key index to determine its safety. According to the relevant literature and experimental data, the explosion limit of n-butyl acrylate ranges from about 1.6 to 18.0 (volume fraction). This means that when the concentration of n-butyl acrylate in the air is within this range, it may cause an explosion when encountering a fire source.

3. Factors Affecting Explosion Limits

1. Temperature and pressure: Changes in temperature and pressure can significantly affect the explosion limit of n-butyl acrylate. Under high temperature or high pressure conditions, the explosion limit range may change, thereby increasing the risk of explosion.

2. Concentration: The concentration of n-butyl acrylate directly affects the possibility of explosion. When the concentration is below the lower explosive limit or above the upper explosive limit, the possibility of explosion will be reduced, but not completely absent.

3. The composition of the mixture: the mixing ratio of n-butyl acrylate and other gases or vapors will also affect the explosion limit. For example, when mixed with inert gas, its explosion limit may be reduced.

4. n-Butyl Acrylate Application Fields

Butyl acrylate is widely used in many fields because of its excellent performance:

1. Coatings: As an important raw material for acrylic resins, n-butyl acrylate is used to make high-performance coatings, such as automotive coatings and architectural coatings.

2. Adhesive: n-Butyl acrylate is an important component in the preparation of pressure-sensitive adhesives and structural adhesives, with good bonding performance and weather resistance.

3. Plastics and rubber: It can also be used to synthesize plastics and rubber to improve the processing performance and physical properties of materials.

5. n-Butyl Acrylate Safety Precautions

1. Storage: Butyl acrylate should be stored in a cool, well-ventilated place, away from fire and oxidant. The storage container shall be closed to avoid volatilization.

2. Transportation: During transportation, avoid high temperature and open fire to ensure that the packaging is intact. Transport vehicles shall be equipped with appropriate safety equipment.

3. Use: When using n-butyl acrylate, wear protective equipment such as gloves, masks, and goggles to prevent direct contact or inhalation of its vapors.

4. Monitoring: In places where there may be leakage of n-butyl acrylate, a gas detector should be installed to monitor its concentration in real time. Once the concentration is close to the explosion limit range, emergency measures should be taken immediately.

6. summary

As an important chemical raw material, the explosion limit of n-butyl acrylate ranges from 1.6 to 18.0 (volume fraction). This indicator is of great significance to ensure the safety of its storage and use. In practical applications, relevant safety regulations should be strictly observed, especially in operations involving n-butyl acrylate, effective explosion-proof measures must be taken to avoid potential explosion risks. Through in-depth understanding of the nature and safety precautions of n-butyl acrylate, the safety of personnel and equipment can be guaranteed to the greatest extent.
