SECTION 10: Stability and reactivity
Reactivity
May decompose explosively on shock, friction or concussion. Decomposes explosively on heating to 187°C. Reacts with some oxidants. This generates fire and explosion hazard.
Chemical stability
Is highly stable losing virtually no weight on prolonged storage at 80 deg C.
Possibility of hazardous reactions
Dangerous fire ... explosion riskDust explosion possible if in powder or granular form, mixed with air.During the measurement of the shock sensitivity of a mixture containing hydrazine, a drop of the hydrazine mixture fell on a tetryl explosive. The tetryl immediately burst into flames (ASESB 105).
Conditions to avoid
no data available
Incompatible materials
Contact of tetryl with some oxidizable materials may cause fires & explosions.
Hazardous decomposition products
When heated to decomposition it emits toxic fumes of /nitrogen oxide/.

Persistence and degradability
Data from composting experiments suggest that biodegradation of tetryl may occur under some conditions(1). When tetryl-contaminated sediment was added to hay-horse feed or sewage sludge-wood chip compost, 90% of the tetryl was removed after 44 days(1). A first-order half-life of 1.2 weeks was calculated for tetryl in a manure-hay-sawdust compost(1). Tetryl was completely biodegraded in a laboratory reactor using a soil slurry amended with molasses over a 3 month operation period(2). Metabolites identified included trinitro-N-methylaniline, trinitrobenzeneamine, dinitrobenzenediamine, nitroaniline and aniline(2). In previous experiments using anoxic conditions and in the absence of co-substrates such as molasses, tetryl and trinitrotoluene (TNT) were not degraded(2).
Bioaccumulative potential
An estimated BCF of 4 was calculated for tetryl(SRC), using an estimated log Kow of 1.64(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).
Mobility in soil
Using a structure estimation method based on molecular connectivity indices(1), the Koc for tetryl can be estimated to be 2,100(SRC). According to a classification scheme(2), this estimated Koc value suggests that tetryl is expected to have slight mobility in soil(SRC). It was demonstrated that nitroaromatic compounds (including tetryl) adsorb strongly to clay minerals in aqueous suspensions, particularly when exchangeable cations in the clays include ammonium and potassium(3).
Other adverse effects
no data available
SECTION 13: Disposal considerations
Disposal methods
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.
