Fumaric Acid Storage — trans-Butenedioic Acid Tank Selection

Storing Fumaric Acid? Start Here

Fumaric acid is a versatile ingredient used in food preservation, animal feed, and polymer resins. If you're handling this white crystalline acid, you need to know how to store it safely. While it's not very soluble in water, it packs a punch as a feed acidifier and is a key player in unsaturated polyester resin production. Let's explore the best ways to store fumaric acid, whether you're working with it in solid form or as a solution.

Can you store it in a poly tank?

Yes, you can store fumaric acid in polyethylene tanks. Both HDPE and XLPE are suitable for storing solid fumaric acid and its aqueous solutions. These materials meet food-grade standards, making them safe for food and technical-grade storage.

Key Issue: Low Solubility

Fumaric acid's low water solubility means it's typically handled as a solid. When solutions are necessary, they're usually prepared in heated tanks at low concentrations (1-3%). This ensures the acid dissolves properly without reaching saturation.

The safety that actually matters

• Use food-grade materials for storage to prevent contamination.
• Handle with care to avoid eye irritation; safety goggles are recommended.
• Ensure proper ventilation to protect aquatic life from potential harm.

Common questions

Can I use stainless steel for storing fumaric acid?

Yes, 316L stainless steel is preferred for high-purity applications, but 304 stainless is also acceptable.

What gasket material should I use?

EPDM is the standard choice for food-grade applications, while Viton is suitable for higher temperatures.

Is fumaric acid regulated for transport?

No, fumaric acid is not regulated for ground or marine transport, making logistics simpler.
