Glyoxal By: Alexis Howes
Molecular Formula: C2H2O2 • Molecular mass: 58.04 g/mol • Density: 1.27 g/cm3 • Melting Point: 15 °C, 288 K, 59 °F • Boiling Point: 51 °C, 324 K, 124 °F • Solubility in Water: Yes • Yellow colored
First made by N. Lubawin in 1875 • It was first commercial source was in Lamotte, France • The simplest dialdehyde- meaning that it’s the smallest form containing two sets of –CHO • Synthesis: CHO—CHO • It can be synthesized in the lab by oxidizing acetaldehyde with selenious acid • This is used on coated paper and in textile finishes as a crosslinker for starch-based formulas • It also cross-links in polymer chemistry: proteins (leather tanning process), collagen, cellulosed derivatives (textiles), hydrocolliods, starch (paper coatings)
Health Effects and toxicity- known to irritate humans on the skin and the mucosal areas, turning the areas red and itchy; if inhaled it may cause loss of breath and coughing; if ingested it may cause nausea and vomiting • Health Hazard Symbol- Blue: Health Hazard; Red: Flammability; Yellow: Reactivity; White: Special Notice Number range- 0-no known hazard 4- most dangerous
