Glyoxal CAS 107-22-2 (40% Aqueous Solution)
Product Introduction
Glyoxal (ethanedial, CAS 107-22-2) is the smallest dialdehyde and one of the most versatile crosslinking intermediates in industrial chemistry. Zorui supplies glyoxal as a 40% aqueous solution, a clear yellow liquid with 40.0% +/- 1.0% assay. Because it reacts with hydroxyl, and imine groups, glyoxal is the preferred formaldehyde-free crosslinker for textile finishing, paper wet-strength resins and leather tanning, and a key starting material for heterocyclic fine chemicals.

Product Functions
- Crosslinking Agent: forms stable bonds with cellulose, collagen and polyamide chains, improving wet strength and shape retention.
- Formaldehyde-Free Resin Component: replaces formaldehyde donors in wrinkle-free textile and paper chemicals.
- Biocide Enhancer: used in synergistic disinfectant and slimicide formulations.
- Chemical Building Block: precursor for imidazoles, pyrazines, glyoxylic acid and other heterocycles.
Application Areas
- Textile Industry: permanent-press and crease-resistant finishing of cotton and blended fabrics.
- Paper Industry: wet-strength resins and coating hardeners.
- Leather Industry: tanning and retanning auxiliary for wet-white leather.
- Coatings & Adhesives: crosslinker for starch, PVA and protein-based systems.
- Fine Chemicals: synthesis of imidazole derivatives, pyrazines and pharmaceutical intermediates.
- Wood & Construction: hardener for wood adhesives and formaldehyde-free board binders.
Manufacturing Process
- Oxidation: ethylene glycol is oxidized in the gas phase over a fixed-bed catalyst with controlled air feed.
- Absorption: reactor effluent is quenched and absorbed into water to form the crude solution.
- Concentration: the solution is concentrated and adjusted to 40% w/w assay.
- Purification: activated carbon treatment and fine filtration remove color bodies and metal ions.
- Quality Control: assay, acidity, iron and appearance are checked per batch; COA issued with each delivery.

FAQ
Q: What concentration of glyoxal do you supply?
A: Our standard product is a 40% aqueous solution; 30% and concentrated grades can be discussed for contract orders.
Q: Can glyoxal replace formaldehyde-based crosslinkers?
A: In many textile, paper and leather applications glyoxal offers a formaldehyde-free crosslinking mechanism with comparable performance.
Q: How should glyoxal solution be stored?
A: Store in original sealed containers at 5-35 °C away from direct sunlight, strong alkalis and oxidizing agents; avoid repeated temperature swings.
Q: What is the shelf life?
A: 12 months from the production date when stored under recommended conditions.
Q: Is a sample available before bulk ordering?
A: Yes, 1kg or 5kg samples are available; samples ship by express at the buyer's cost.
