Diethylzinc (DEZ), a highly reactive organometallic compound with CAS number 557-20-0, is an indispensable tool in modern organic synthesis and materials science. However, its pyrophoric nature—meaning it ignites spontaneously upon contact with air—demands strict adherence to safety protocols. As a reputable manufacturer and supplier, understanding and implementing safe handling practices is paramount for any professional working with this powerful reagent.

Understanding the Hazards of Diethylzinc

The primary hazard associated with Diethylzinc is its extreme flammability and reactivity with air and moisture. It can also react violently with water, potentially leading to explosions. This necessitates the use of specialized equipment and techniques, such as air-free manipulation using Schlenk lines or glove boxes. The compound is often supplied as a solution in hydrocarbon solvents like hexane or heptane to mitigate some of these risks, but it remains highly reactive.

Best Practices for Storage and Handling

When you buy Diethylzinc, proper storage is the first line of defense. It should be kept in tightly sealed containers, under an inert atmosphere (typically nitrogen or argon), and away from any sources of ignition, heat, or moisture. Storage areas should be well-ventilated and equipped with appropriate fire suppression systems designed for metal fires. Always consult the Safety Data Sheet (SDS) provided by your supplier, such as ourselves as a leading manufacturer in China, for specific storage recommendations.

During handling, always wear appropriate personal protective equipment (PPE). This includes flame-resistant laboratory coats, chemical-resistant gloves (like nitrile or neoprene), and safety goggles or a face shield. Transfers should be conducted using inert gas techniques to exclude air. For precise additions, cannulas or syringes specifically designed for air-sensitive materials are essential. Never use standard syringes as they are not designed for pyrophoric liquids and can lead to dangerous leaks.

Emergency Procedures and Disposal

In the event of a fire involving Diethylzinc, never use water, carbon dioxide, or standard dry chemical extinguishers. Instead, use Class D fire extinguishers designed for combustible metals, or smother the fire with dry sand or vermiculite. If accidental skin contact occurs, immediately brush off any excess material and then flush the affected area with copious amounts of water. Seek immediate medical attention.

Disposal of Diethylzinc waste must be handled with extreme caution and in accordance with local regulations. Quenching procedures, often involving slow addition to a less reactive solvent or a carefully controlled reaction to deactivate the compound, should only be performed by experienced personnel. As a responsible Diethylzinc supplier, we can provide guidance on safe disposal methods.
