Physicochemical Properties:
　　Glyoxal is the simplest dual aldehyde, the molecular formula is OHCCHO and the molecular weight is 58, pure glyoxal monomer is achromatic or light yellow crystal or liquid, with a proportion (d20 °C ) 1.26, melting points 15°C , boiling point 50.5 °C and refractive index 1.3826. The glyoxal steam is green, when burning, it sends out purple flame. Glyoxal can dissolve in water, aether and ethaol

Industrial glyoxal usually exists in watery solution by about 40% water content. Besides the reaction nature of all the aldehyde, glyoxal has special chemical property for its two coordinate functional groups.

The reaction of glyoxal watery solution is same with that of the single molecular glyoxal. The majority reactions are substitution reactions which two hydroxyl atoms occur. Glyoxal reacts with the compound in the centre of the individual nucleophilic, and results in line-type moleculars. Glyoxal reacts with the compound in the centre of the two stable nucleophilic and results in reactions of cyclocompounds, but prepares many fine chemical products, medicine and the medicine intermediates.

Packing, transportation, store:

1.logo: Each batch of glyoxal has got a certificate, the factory name, the product range, the batch number, the content and the product net weight.

2. packing: it may be loaded in barrels, bulks as well as the 1000L special-purpose packing. The loaded in barrels uses the dry and clean polyethylene plastic barrels with net weight 250KG. It uses the stainless steel accumulator tank car in bulk to transport.

3. transportation: use the automobile, the train or the ship for the transportation.

4. storing: The glyoxal must be stored in clean, cool ventilated warehouse, the storing deadline counted from the production date is 6 months.
