How to safely store aniline

Aniline (Aniline) is an important organic compound, which is widely used in the production of dyes, rubber auxiliaries and drugs in the chemical industry. Aniline has a certain toxicity and volatility, and flammable, so how to safely store aniline is particularly important. In this article, we will analyze in detail the relevant precautions and methods for the safe storage of aniline to help you effectively avoid potential risks.

1. Storage conditions

Aniline should be stored in a cool, dry, well-ventilated environment. Aniline has a boiling point of 184°C and is a volatile liquid at room temperature, so it must be protected from exposure to high temperatures during storage to avoid evaporation and volatilization. It is recommended to store it away from heat and fire sources, and keep the ambient temperature as low as possible below 25°C.

2. Storage container selection

Aniline is corrosive to some metals, especially after contact with moisture. Therefore, corrosion-resistant containers should be used when storing aniline. recommend choose tanks or containers made of stainless steel, nickel or nickel alloy to avoid leakage caused by corrosion. The container needs to be well sealed to prevent volatilization of aniline, and the sealing and structural integrity of the container should be checked regularly.

3. Fire prevention measures

Aniline is a flammable chemical despite its high flash point (about 70°C). Therefore, fire prevention measures must be taken in the place where aniline is stored. Adequate fire fighting equipment shall be provided in the warehouse, such as fire extinguishers, sand extinguishing and water mist spraying devices. Smoking or the use of open fire equipment in the storage area of aniline shall be strictly prohibited, and the storage area of aniline shall have explosion-proof lighting and ventilation system to prevent accidental fire.

4. Avoid contact with incompatible substances

Aniline should be stored to avoid contact with strong oxidants such as nitric acid, hydrogen peroxide, etc. Contact with strong oxidizing agents can trigger violent chemical reactions that can lead to fire or explosion. Therefore, aniline should be stored separately from these incompatible substances, preferably in a separate area or room, and clearly marked.

5. Leakage emergency treatment

If aniline leaks, immediate emergency measures must be taken. Wear protective equipment (such as protective gloves, goggles, and gas masks) to avoid contact with aniline. Then, quickly ventilate to prevent steam accumulation. Adsorbing materials (such as sand or activated carbon) are used to absorb the leaked liquid, and then the waste is properly disposed. If the leakage is large, it is necessary to evacuate the site personnel and contact the professional dangerous goods handling team.

6. Safety identification and records

To ensure safe storage of aniline, it should be clearly identified. Storage areas and containers shall be clearly marked with "Aniline" and its hazardous properties, and with handling precautions. Detailed storage records shall be established, including the entry and exit of aniline, storage location, custodian and regular safety inspection records.

Conclusion

The safe storage of aniline needs to be strictly controlled from many aspects such as storage conditions, container selection, fire prevention measures, material isolation, emergency treatment and safety management. Only by considering these factors comprehensively can we avoid the possible risks during the storage of aniline to the greatest extent, so as to ensure the safety of operators and the protection of the environment.

By mastering these key points for safe storage of aniline, you can not only effectively prevent accidents, but also ensure the stability of aniline and provide a good foundation for its subsequent use.
