Glyoxal Storage — Dialdehyde Crosslinker Tank Selection

Storing Glyoxal? Start Here

Glyoxal is widely used in industries like paper manufacturing, textiles, and leather tanning. It's typically supplied as a 40% aqueous solution, which is a clear, pale-yellow liquid with a sharp odor. Though non-flammable, it can cause skin and eye irritation, so proper handling is essential. If you're considering storing glyoxal, understanding its properties and compatibility with storage materials is crucial.

Can you store it in a poly tank?

Yes, glyoxal's 40% aqueous solution is compatible with most plastics, including HDPE and XLPE, which are standard for bulk industrial storage tanks. Polypropylene is also suitable for fittings and pump bodies. Avoid using carbon steel and aluminum due to their susceptibility to acid corrosion.

Watch out for freezing

Glyoxal's aqueous solution has a freezing point of 14°C (57°F). If you're storing it outdoors in colder climates, you might need to add heat tracing to your tank and piping to keep the solution from freezing.

The safety that actually matters

  • Use Viton gaskets for optimal compatibility and to prevent leaks.
  • Avoid skin and eye contact to prevent irritation and potential allergic reactions.
  • Ensure proper ventilation to minimize inhalation risks.

Common questions

What type of tank is best for storing glyoxal?
HDPE rotomolded tanks with polypropylene fittings are standard for glyoxal storage.
Do I need special gaskets?
Yes, use Viton gaskets for the best chemical resistance with glyoxal.
Is glyoxal flammable?
No, the 40% aqueous solution of glyoxal is non-flammable.
