How to safely store acetonitrile

Acetonitrile (Acetonitrile) is a chemical solvent commonly used in chemical experiments, pharmaceuticals and organic synthesis, but due to its volatility and flammability, safe storage is very important. This article details how acetonitrile can be safely stored to help ensure safety in a laboratory or industrial environment.

1. Understand acetonitrile chemical properties

Before discussing how to safely store acetonitrile, it is first necessary to understand its chemical properties. Acetonitrile is a colorless liquid with a faint ether odor, strong volatility, and a low flash point (about 6°C). It is not only flammable, but also may produce toxic gases. Therefore, storage of acetonitrile requires special attention to its flammability and potential toxicity. Acetonitrile is corrosive, and long-term contact may cause damage to metal and some plastic materials.

2. Choose the right storage container

To ensure safe storage of acetonitrile, the use of a suitable container is critical. Acetonitrile should be stored in sealed containers, usually recommend stainless steel or treated glass containers. Containers shall be designed to prevent static electricity from causing sparks. If you use plastic containers, make sure that the plastic is resistant to acetonitrile and solvents, such as high-density polyethylene (HDPE) or polytetrafluoroethylene (PTFE).

3. Storage environment requirements

Acetonitrile should be stored in a dry and well-ventilated place, away from heat and fire sources, and avoid direct sunlight. The storage temperature should be below its flash point (6°C) to reduce vapor generation. The ideal storage environment is a thermostatically controlled chemical storage room with appropriate explosion-proof ventilation to prevent vapor accumulation in the air. Fire alarm system and fire extinguishing equipment shall be installed in the storage area.

4. Safety protection measures

In the storage area of acetonitrile, clear safety signs should be posted to warn of its flammability and toxicity. Personnel should wear protective equipment such as protective gloves, goggles and protective clothing when handling acetonitrile to prevent skin and eye contact with acetonitrile. Ensure storage sites are equipped with appropriate emergency eyewash devices and first aid equipment to deal with accidental spills or contact incidents.

5. Leakage treatment and emergency measures

Although preventive measures have been taken during storage, emergency plans for acetonitrile leakage treatment are still needed. In the event of a leak, first of all, evacuate irrelevant personnel immediately, shut down all sources of ignition, and quickly dispose of the spill with adsorbent materials (such as activated carbon or dry sand). During the treatment, the operator should wear a full set of protective equipment to ensure their own safety.

6. Acetonitrile storage laws and regulations

When storing acetonitrile, it is also necessary to comply with relevant laws and regulations. In most countries, acetonitrile is classified as a hazardous chemical and storage must meet the requirements of the Hazardous Chemicals Safety Management Regulations or similar regulations. Enterprises should regularly inspect storage facilities and conduct safety training for staff to ensure that they have the ability to operate correctly and deal with emergencies.

Summary

The safe storage of acetonitrile (Acetonitrile) requires a comprehensive consideration of its chemical properties, storage containers, environmental requirements, safety precautions and emergency treatment. By following the above steps, you can effectively reduce the potential risks posed by acetonitrile and ensure the safe operation of the laboratory or plant. In daily management, enterprises should constantly update safety measures to avoid accidents caused by negligence.
