10.2 Chemical stabilityOxidises slowly on exposure to air, forming isobutyric acid.
10.3 Possibility of hazardous reactionsA very dangerous fire hazard when exposed to heat, flame, or oxidizers.The vapour is heavier than air and may travel along the ground; distant ignition possible.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.

AEROBIC: Using a sewage inocula and standard dilution water, isobutyraldehyde had a 5-day theoretical BOD of 66%(2). Isobutyraldehyde was found to be readily biodegradable in a screening study using activated sludge (more specific data were not reported)(2). In an anaerobic screening study simulating a biological treatment plant (digester sludge inocula), isobutyraldehyde experienced a 71% removal at retention times of 144-240 hr(3). In a screening study simulating an anaerobic lagoon (digester sludge inocula), isobutyraldehyde experienced a 76% removal at retention times of 240-2400 hr(3). Using a Warburg respirometer, an activated sludge seed, and a 24-hr incubation period, isobutyraldehyde had a theoretical BOD of 24.3% at an initial concn of 500 ppm(4). Isobutyraldehyde, present at 100 mg/l, reached 81% of its theoretical BOD in 2 weeks using an activated sludge inoculum at 30 mg/l and the Japanese MITI test(5).
12.3 Bioaccumulative potentialAn estimated BCF of 1 was calculated for isobutyraldehyde(SRC), using a water solubility of 89,000 mg/l(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is low(SRC).
12.4 Mobility in soilThe Koc of isobutyraldehyde is estimated as 8(SRC), using a water solubility of 8.9X10+4(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that isobutyraldehyde is expected to have very high mobility in soil(SRC).
12.5 Other adverse effectsno data available
13.Disposal considerations 13.1 Disposal methods ProductThe material can be disposed of by removal to a licensed chemical destruction plant or by controlled incineration with flue gas scrubbing. Do not contaminate water, foodstuffs, feed or seed by storage or disposal. Do not discharge to sewer systems.
Contaminated packagingContainers can be triply rinsed (or equivalent) and offered for recycling or reconditioning. Alternatively, the packaging can be punctured to make it unusable for other purposes and then be disposed of in a sanitary landfill. Controlled incineration with flue gas scrubbing is possible for combustible packaging materials.
