Decomposes on burning. Decomposes on contact with hot surfaces, flames or acids. This produces toxic and corrosive fumes including hydrogen cyanide and nitrogen oxides. Reacts violently with strong acids, strong bases, strong oxidants and strong reducing agents.

FLAMMABLE, DANGEROUS FIRE RISK.The vapour mixes well with air, explosive mixtures are easily formed.BUTYRONITRILE can react vigorously with oxidizing reagents, when heated to decomposition, it emits highly toxic fumes of cyanides and oxides of nitrogen [Sax, 9th ed., 1996, p. 609]. Nitriles may polymerize in the presence of metals and some metal compounds. They are incompatible with acids; mixing nitriles with strong oxidizing acids can lead to extremely violent reactions. Nitriles are generally incompatible with other oxidizing agents such as peroxides and epoxides. The combination of bases and nitriles can produce hydrogen cyanide. Nitriles are hydrolyzed in both aqueous acid and base to give carboxylic acids (or salts of carboxylic acids). These reactions generate heat. Peroxides convert nitriles to amides. Nitriles can react vigorously with reducing agents. Acetonitrile and propionitrile are soluble in water, but nitriles higher than propionitrile have low aqueous solubility. They are also insoluble in aqueous acids.

The vapour is mildly irritating to the eyes, skin and respiratory tract. The substance may cause effects on the cellular respiration (inhibition). This may result in convulsions, cardiac disorders and respiratory failure. Exposure at high levels could cause death. The effects may be delayed. Medical observation is indicated.

A harmful contamination of the air can be reached rather quickly on evaporation of this substance at 20°C , on spraying or dispersing much faster.
AEROBIC: Enzyme-catalyzed hydrolysis of nitriles has been shown to proceed by two distinct routes(1,2); a nitrilase transforms the nitriles directly into acids plus ammonium ion, or a nitrile hydratase forms the amide which is hydrolyzed to acid plus ammonium ion by amidase(1,2). A predictive method based upon evaluated biodegradation data and the fact that butanenitrile contains a nitrile substructure predicts that butanenitrile has a high probability of biodegrading fast in the environment(3). A mixed microbial culture, isolated from an environment contaminated with organic cyanides and PCBs, utilized butanenitrile as the sole source of carbon and nitrogen(4). The mixed microbial culture was grown for 48 hrs at pH 7 with 1 g/l of butanenitrile; the final pH and ammonia concn were determined to be 8.69 and 74.6 umol/ml, respectively(4). Isobutanenitrile, a chemical whose structure is similar to butanenitrile, has been shown to biodegrade readily using the Japanese MITI protocol (2 wk incubation, 100 ppm concn) with theoretical BODs of 53.9-66.3%(5,6). In addition, acetonitrile, which is structurally similar to butanenitrile, has been shown to biodegrade readily in river water, especially with acclimated microbes(7,8). Thus, butanenitrile may be expected to biodegrade in the environment(SRC).
An estimated BCF of 3 was calculated for butanenitrile(SRC), using a log Kow of 0.53(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).
The Koc of butanenitrile is estimated as 46(SRC), using a measured log Kow of 0.53(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that butanenitrile is expected to have very high mobility in soil(SRC).

The 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.
Containers 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.
