Acetonitrile (CAS 75-05-8), while an exceptionally useful polar aprotic solvent for organic synthesis and butadiene purification, presents significant safety considerations due to its high flammability. Proper handling and storage protocols are not merely recommendations but necessities to prevent accidents and ensure a safe working environment. Chemical professionals must be thoroughly aware of acetonitrile properties and potential hazards.

The most critical property to address is its flammability. With a flash point of just 2°C, acetonitrile can easily ignite in the presence of an ignition source, including sparks, open flames, and hot surfaces. Therefore, all operations involving acetonitrile should be conducted in well-ventilated areas, away from potential ignition sources. Grounding and bonding of equipment are essential to prevent static electricity discharge, which can act as an ignition source. Storage areas must be designated as flammable liquid storage, equipped with appropriate fire suppression systems.

Another vital aspect is understanding acetonitrile's incompatibilities. As stated in its properties, it is unstable and reacts vigorously or dangerously with alkali metals, acids, bases, reducing agents, and oxidizing agents. Accidental mixing of these substances can lead to fires, explosions, or the release of toxic gases. Therefore, strict segregation of chemicals is crucial in storage and laboratory settings. When performing reactions, the careful, controlled addition of reagents is paramount.

Recommended storage conditions for acetonitrile are typically between 2-8°C to maintain its stability and minimize vapor pressure. This temperature range helps to reduce the risk of ignition. Containers should be tightly sealed to prevent the escape of flammable vapors. For procurement, choosing a reliable acetonitrile supplier like NINGBO INNO PHARMCHEM CO.,LTD. ensures that the product is supplied in appropriate packaging, adhering to safety standards.

By diligently following these best practices for safe handling and storage, chemical professionals can mitigate the risks associated with acetonitrile and continue to harness its valuable chemical properties effectively and responsibly.
