Glyoxal Solution *0% :-

Glyoxal is the simplest dual aldehyde, the molecular formula is OHCCHO and the molecular weight is *8, pure glyoxal monomer is achromatic or light yellow crystal or liquid, with a proportion (d*0 °C ) 1.*6, melting points *5°C , boiling point *0.5 °C and refractive index 1.***6. The glyoxal steam is green, when burning, it sends out purple flame. Glyoxal can dissolve in water, aether and ethaolIndustrial glyoxal usually exists in watery solution by about *0% 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.

The industrial glyoxal usually exists by watery solution of *0% content. It is an important fine chemical product which is widely used in medicine and agriculture. Its sub-products include: *- methyl imidazole, imidazole, *- methyl **- nitryl imidazole, meth-nitrylzole, dimeizole, clotrimazole; they also include glyoxalic acid with its sub-products of hordenine glycine, hordenine mattress, hordenine ethanoic acid and so on; they can also applied in industry, papermaking, spinning and weaving, leather processing, dying, water treatment, building materials and national defense..
