Glyoxal 40% Tech Grade

Our range of Glyoxal 40% Tech Grade 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 A C ) 1.26, melting points 15A C , boiling point 50.5 A 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.
