Hydroxylamine Storage — NH2OH Reactive-Chemical Tank Selection

Storing Hydroxylamine? Start Here

If you're dealing with hydroxylamine, you're handling a powerful reducing agent used in semiconductor and pharmaceutical applications. It's crucial to know that hydroxylamine can be hazardous, especially when contaminated with metals like iron, copper, or nickel. Such contamination can lead to violent reactions, as tragically demonstrated by the 1999 explosion in Pennsylvania. Always prioritize safety and ensure your storage solutions are up to the task.

Can you store it in a poly tank?

Yes, you can store hydroxylamine in polyethylene tanks, but it's essential to avoid any metal contamination. Polypropylene and PVDF are also suitable materials. Stainless steel and other metal tanks are not recommended due to the risk of catalytic decomposition.

Keep an Eye on Metal Contamination

The key issue with hydroxylamine is its sensitivity to metal contamination. Even trace amounts of metals like iron, copper, or nickel can trigger dangerous reactions. Always ensure that your storage system is free from these metals to prevent any hazardous incidents.

The safety that actually matters

• Use only all-polymer or specialty metal tanks like tantalum or zirconium.
• Regularly inspect for and eliminate any potential metal contamination sources.
• Follow strict handling protocols to prevent accidents.

Common questions

Can hydroxylamine be stored in stainless steel tanks?

No, stainless steel is not suitable due to its iron and nickel content, which can cause decomposition.

What materials are safe for hydroxylamine storage?

Polyethylene, polypropylene, PVDF, and specialty metals like tantalum and zirconium are safe choices.

What precautions should I take when storing hydroxylamine?

Ensure no metal contamination, use appropriate tank materials, and follow safety protocols diligently.
