Air and Water Reactions:Highly flammable. Oxidizes slowly on exposure to air. Stable (less than 10% decomposition) for four hours when exposed to light and air in a closed system. Stable for two weeks when stored under nitrogen at temperatures up to 77°F. Insoluble in water.
Reactive Group:Aldehydes
Reactivity Alerts:Highly Flammable
Reactivity Profile:ISOBUTYL ALDEHYDE can react vigorously with reducing agents, with oxidizing agents, strong bases and mineral acids. Can undergo exothermic self-condensation or polymerization reactions that are often catalyzed by acid. Generates flammable and/or toxic gases in combination with azo, diazo compounds, dithiocarbamates, nitrides, and strong reducing agents. Reacts slowly when exposed to air with air to give peroxides and other products. These reactions are activated by light, catalyzed by salts of transition metals, and are autocatalytic (catalyzed by their products). The addition of stabilizers (antioxidants) retards autoxidation.
