glyoxal 40%


Glyoxal 40% Cas No: 107-22-2 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. ZXCHEM GROUP
