Glyoxal Usage And Synthesis

Chemical Properties	colourless or light yellow liquid
General Description	Yellow crystals melting at15°C. Hence often encountered as a light yellow liquid with a weak sour odor. Vapor has a green color and burns with a violet flame.
Air & Water Reactions	Mixtures with air may explode. Polymerizes quickly on standing, or on contact with a trace of water (possibly a violent reaction), or when dissolved in solvents containing water, [Merck, 502(1968)]. Soluble in water. An aqueous solution contains mono molecular Glyoxal. [Hawley]
Reactivity Profile	Glyoxal reacts vigorously with strong oxidizing agents such as nitric acid. Polymerizes rapidly even at low temperature if anhydrous [Noller]. Aqueous solutions are more stable but also polymerize on standing. Reacts with itself in the presence of base to give glyconates. Undergoes addition and condensation reactions that may be exothermic with amines, amides, aldehydes, and hydroxide-containing materials. Mixing in equal molar portions with any of the following substances in a closed container caused the temperature and pressure to increase: chlorosulfonic acid, oleum, ethyleneimine, nitric acid, sodium hydroxide [NFPA 1991].
Health Hazard	Inhalation causes some irritation of nose and,40% solution throat. Contact with liquid,40% solution irritates eyes and causes mild irritation of skin; stains skin yellow. (No information available on symptoms of ingestion.)
Fire Hazard	Behavior in Fire: Heat may cause polymerization to a combustible, viscous material.
