Air & Water Reactions
Highly flammable. Insoluble in water.
A clear colorless liquid with a pungent odor. Flash point 90°F. Less dense than water and insoluble in water. Vapors heavier than air.
Caproaldehyde is an aldehyde. Aldehydes are frequently involved in self-condensation or polymerization reactions. These reactions are exothermic; they are often catalyzed by acid. Aldehydes are readily oxidized to give carboxylic acids. Flammable and/or toxic gases are generated by the combination of aldehydes with azo, diazo compounds, dithiocarbamates, nitrides, and strong reducing agents. Aldehydes can react with air to give first peroxo acids, and ultimately carboxylic acids. These autoxidation reactions are activated by light, catalyzed by salts of transition metals, and are autocatalytic (catalyzed by the products of the reaction). The addition of stabilizers (antioxidants) to shipments of aldehydes retards autoxidation. May attack some forms of plastics [USCG, 1999].
Ingestion causes irritation of mouth and stomach. Contact with vapor or liquid irritates eyes. Liquid irritates skin.
Behavior in Fire: Vapor is heavier than air and may travel to a source of ignition and flash back.
ChEBI: A fatty aldehyde that is hexane in which one of the terminal methyl group has been mono-oxygenated to form the corresponding aldehyde.
