Propylene Carbonate Storage — Cyclic Carbonate Solvent Tank Selection

Storing Propylene Carbonate? Start Here

Propylene carbonate is a versatile liquid used in various industrial applications, including lithium battery electrolytes and as a solvent in polymer processes. Known for its low toxicity and biodegradability, it's a preferred choice for green chemistry. When storing this chemical, it's crucial to understand its properties and compatibility with different materials to ensure safe and effective storage.

Can you store it in a poly tank?

Yes, propylene carbonate can be stored in polyethylene tanks. It's broadly compatible with HDPE and XLPE, making them suitable for bulk industrial storage. For high-purity applications, consider using stainless steel or fluoropolymer-lined tanks.

Key Issue: Low Freezing Point

Propylene carbonate has a low freezing point of -49°C, which means it's generally stable in most climates. However, if you're operating in extreme arctic conditions, you might need to consider additional measures like heat tracing to prevent freezing.

The safety that actually matters

• Ensure tanks and fittings are compatible with propylene carbonate.
• Use appropriate gaskets, such as EPDM or Viton, based on your specific service conditions.
• Maintain a nitrogen blanket for vapor space management in high-purity applications.

Common questions

Is propylene carbonate safe to store outdoors?

Yes, but ensure the tank is suitable for the climate to prevent freezing in extreme cold.

What materials are best for gaskets?

EPDM or Viton are commonly used; always refer to the manufacturer's compatibility chart.

Can I use a standard polyethylene tank for battery-grade storage?

No, for battery-grade storage, stainless steel tanks with specific fittings are recommended.
