Glyoxal CAS 107-22-2

Glyoxal CAS 107-22-2

Glyoxal, also known as oxalate aldehyde, with the molecular formula C2H2O2, is a light yellow slightly irritating liquid that is easily soluble in water, alcohol, and ether. The vapor is green and burns with a purple flame. Quickly polymerize when placed, in contact with water (violent reaction), or dissolved in aqueous solvents. Usually exists in various aggregated forms. When heated, anhydrous polymers transform back into monomers. The aqueous solution of glyoxal is weakly acidic and can be evaporated under vacuum to obtain poly (glyoxal) or trimeric glyoxal. The products sold on the market are mostly glyoxal aqueous solutions with a concentration of 30% -40%, which exist in the form of tetraalcohols.
Glyoxal (40%) aqueous solution is a colorless or light yellow transparent liquid. Glyoxal aqueous solution is very stable and exists in the form of hydrates, with almost no volatilization. The chemical properties are very active, and it is easy to produce resin like solid polymers when placed.

Specification

Application

Textile Industry (Main Application)

1. Cotton fabric anti-stretching and anti-wrinkling finishing agents, replacing some formaldehyde-containing resins, improving the fabric’s anti-wrinkling and rebound performance;
2. Artificial silk and viscose fiber anti-shrinkage agents, reducing the fabric’s shrinkage rate;
3. Fiber fixation and post-treatment agents.

Paper Industry

1. Paper wet strength agent, mixed with starch and PVA, increasing the paper’s water resistance;
2. Coating paper coating crosslinking agent, Glyoxal improving the coating’s water resistance and anti-fall-off powder;
3. Paper pulp modification treatment.

Adhesives & Wood Processing

1. Modified urea-formaldehyde resin, reducing the free formaldehyde content in the glue and improving the glue layer’s water resistance;
2. PVA polyvinyl alcohol glue crosslinking agent, enhancing the glue’s water resistance and temperature resistance;
3. Wood and artificial board additives.

Leather Industry

Leather retanning agent, Glyoxal CAS 107-22-2 used in leather tanning, making the leather feel full.

Fine Chemicals, Pharmaceutical and Pesticide Intermediates

1. Synthesis of imidazole compounds, glyoxal derivatives;
2. Glyoxal synthesis of fungicides: imazalil, tridiazolidinyl urea, etc. as pesticide intermediates;
3. Synthesis of various heterocyclic pharmaceutical raw materials.

Water Treatment

Boiler circulating water oxygen remover, removing dissolved oxygen in water, slowing down the corrosion of pipeline equipment.

Other Small Applications

– Building coatings, coating crosslinking modification;
– Gel, resin synthesis;

Package and Storage

250kg/drum or requirement of clients.

Store in a sealed, cool and ventilated warehouse. The storage temperature should be between 5 and 25 degrees Celsius. Do not exceed 30 degrees Celsius; high temperatures will accelerate self-polymerization. Avoid light; store separately from strong alkalis, oxidants, and food chemicals; seal the packaging to reduce contact with air; the storage area should be equipped with leakage protection facilities.

FAQ

Q: How long is the shelf life?
A: In the original sealed packaging, it lasts for 6 to 12 months; the higher the temperature, the shorter the shelf life; use it up as soon as possible after opening; check for any white flocculent precipitate before use.

Q: Can it still be used if there is a white flocculent substance?
A:Glyoxal is a self-polymerization phenomenon; a small amount can be re-solubilized by heating; if there is a lot of flocculent substance and the color deepens, it becomes ineffective and must not be used; the storage temperature must not exceed 25℃.

Q: What is the minimum order quantity? Can samples be provided?
A: For regular bulk orders, the minimum order quantity is 25kg in plastic barrels; for small-scale trials, samples ranging from 100g to 1kg can be provided, along with COA (Certificate of Analysis) and MSDS (Material Safety Data Sheet); the sample price is higher than that of the bulk order; the mainstream specification is glyoxal 40% aqueous solution; bulk packaging: 25kg barrels, 200kg barrels, IBC (Intermediate Bulk Container) tons barrels.

Q: What is the delivery cycle?
A: Industrial-grade 40% aqueous solution is available in stock; upon payment confirmation, the order will be dispatched within 2-3 working days; special refined specifications require production scheduling of 7-12 working days; confirm inventory before placing the order.

Q: What kind of materials can be provided? Is invoicing available?
A: Invoicing is available; COA (Certificate of Analysis) and MSDS (Material Safety Data Sheet) can be provided.
