isobutyraldehyde usage and synthesis

chemical properties	colourless liquid with an extremely unpleasant smell
general description	a clear colorless liquid with a pungent odor. flash point of -40°f. less dense than water and insoluble in water. hence floats on water. vapors are heavier than air. used to make other chemicals.
air & 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.
reactivity profile	isobutyraldehyde 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.
health hazard	vapor is irritating to the eyes and mucous membranes.
fire hazard	behavior in fire: vapors are heavier than air and may travel considerable distance to a source of ignition and flash back. fires are difficult to control due to ease of reignition.
