Succinic Acid Storage — Butanedioic Acid Tank Selection

Storing Succinic Acid? Start Here

Succinic acid is a versatile chemical used in food, pharmaceuticals, and bioplastics. It's a white crystalline substance that dissolves moderately in water, becoming more soluble as the temperature rises. While it’s generally safe, it can cause serious eye irritation, so handling it with care is important. Whether you're using it as a food acidulant or in specialty chemical applications, knowing the right storage methods is key to maintaining its quality and safety.

Can you store it in a poly tank?

Yes, you can store succinic acid in a polyethylene tank. Both HDPE and XLPE tanks are suitable for storing succinic acid solutions, making them a standard choice for food and technical-grade storage. These materials are compatible with succinic acid due to its mild acidity and chemical stability.

Key Issue: Material Compatibility

When storing succinic acid, material compatibility is crucial. While polyethylene is suitable, other materials like 316L stainless steel or polypropylene are often used for fittings and pump bodies, especially in pharmaceutical and food-grade applications. Avoid using materials like galvanized steel or copper, as they can contaminate the acid over time.

The safety that actually matters

• Always use appropriate eye protection to prevent irritation.
• Ensure that storage tanks are compatible with succinic acid.
• Regularly inspect tanks and fittings for signs of wear or corrosion.
• Follow all relevant safety guidelines and regulations for handling chemicals.

Common questions

Can succinic acid be stored in stainless steel tanks?

Yes, 316L stainless steel is ideal for high-purity applications and is preferred for its resistance to corrosion.

Is succinic acid safe for food applications?

Yes, it is Generally Recognized as Safe (GRAS) by the FDA for use as a food acidulant and flavor enhancer.

What gasket material should I use?

EPDM gaskets are standard for food-grade applications, but always match gaskets to the manufacturer’s compatibility chart.
