Characteristics-
PSA:
34.14000
XLogP3:-0.61580
Appearance:Glyoxal appears as 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.
Density:1.14 g/cm3 @ Temp: 20 °C
Melting Point:15 °C
Boiling Point:51 °C @ Press: 776 Torr
Flash Point:285ºC
Refractive Index:n20/D 1.409
Water Solubility:Micible with water.
Storage Conditions:2-8ºC
Vapor Pressure:18 mm Hg ( 20 °C)
Vapor Density:>1 (vs air)
Toxicity:LD50 in rats, guinea pigs (mg/kg): 2020, 760 orally (Smyth)
Explosive limit:Mixing glyoxal and /chlorosulfonic acid, ethyleneimine, oleum, nitric acid, or sodium hydroxide/...in a closed container caused temperature and pressure to increase.
Odor:Mild odor
PH:pH of 40% aqueous solution = 2.1 to 2.7
OH:1.14e-11 cm3/molecule*sec
Henrys Law Constant:3.33e-09 atm-m3/mole|Henry's Law constant = 3.33X10-9 atm-cu-m/mol at 25 °C
Experimental Properties:10.0 lb/gallon at 20 °C; burns with violet flame; aqueous solution contains monomolecular glyoxal and reacts weakly with acid; glyoxal VP resists discoloration; undergoes many addition & condensation reactions with amines, amides, aldehydes & hydroxyl-containing materials.|Glyoxal is oxidized by dilute nitric acid to glyoxyl acid, & by concentrated nitric acid to oxalic acid|Anhydrous polymer changes to monomer on heating; non-hygroscopic; crystalline powder; more soluble in hot water than in cold water /Dihydrate/|Conversion factors: 1 mg/L= 422 ppm; 1 ppm= 2.4 mg/cu m|Hydroxyl radical reaction rate constant = 1.14X10-11 cu cm/molec-sec at 25 °C
Air and 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]
Reactive Group:Aldehydes
Reactivity Alerts:Polymerizable
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].
Autoignition Temperature:545 °F (NTP, 1992)|285 °C
Critical Temperature & Pressure:Critical temperature = 495 K; critical pressure = 5.88X10+6 Pa
