10.3 Possibility of hazardous reactionsCombustibleDust explosion possible if in powder or granular form, mixed with air.Dust explosion possible if in powder or granular form, mixed with air.DINITROBENZENE SOLUTION may react vigorously with oxidizing materials. Reaction with nitric acid (nitration) leads to a mixture of trinitrobenzenes possessing high-explosive properties [Urbanski, 1967, vol. 3, p. 290]. If heat and reaction conditions of the nitration are not controlled, detonation comparable to that of TNT may occur [Anon., J. R. Inst. Chem., 1960, 84, p. 451]. A mixture of 1,3-dinitrobenzene with tetranitromethane can be highly explosive [Urbanski, 1964, vol. 1, 592]. 1,2-dinitrobenzene is a severe explosion hazard when shocked or exposed to heat or flame.

- Toxicity to microorganisms: no data available
Anaerobic and aerobic incubation of 1,3-dinitrobenzene with sewage effluent at 29°C resulted in about 85% and 40% degradation after 28 days, respectively(1). The products of the anaerobic incubations were aromatic amines while under aerobic conditions, ring cleavage and possible mineralization of 1,3-dinitrobenzene occurred(1). More than 64 days were required to achieve a total loss of 1,3-dinitrobenzene when incubated with Niagara silt loam inoculum at 25°C(2). Microorganisms isolated from the Tennessee River near a munitions production facility were shown to biodegrade 1,3-dinitrobenzene(3). At 1X10+6 microorganisms/mL and 25°C, the half-life of 1,3-dinitrobenzene in river water samples and enrichment cultures were 1 and 9.7 days, respectively(3). However, 1,3-dinitrobenzene did not biodegrade in pristine river and creek water from Maryland, suggesting that microbial adaptation is necessary for degradation to occur(3). After 3 hr incubation at 30°C with phenol adapted bacteria from soil and related environments, 75% of the initial amount of 1,3-dinitrobenzene was degraded(4). Dinitrobenzene (isomer not specified), present at 100 mg/l, reached 0 percent of its theoretical BOD in 2 weeks using an activated sludge inoculum at 30 mg/l and the Japanese MITI test(5), suggesting biodegradation occurs slowly(SRC).
12.3 Bioaccumulative potentialA BCF value of 75 was measured for 1,3-dinitrobenzene in fish(1). BCF values of 2-38 were measured in carp exposed to dinitrobenzene (isomer not specified) over a 6 week incubation period(2). According to a classification scheme(3), this BCF value suggest bioconcentration in aquatic organisms is low to moderate(SRC).
12.4 Mobility in soilThe Koc of 1,3-dinitrobenzene is estimated as 150(SRC), using a measured log Kow of 1.49(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that 1,3-dinitrobenzene is expected to have high mobility in soil. It has been shown that nitrophenols and nitrobenzenes adsorb strongly to clay through an interaction between the nitro group and the water molecules or metallic cations in the clay(4), and 1,3-dinitrobenzene is expected to similarly bind to clays(SRC). The adsorption of 1,3-dinitrobenzene was studied in montmorillonite, clay and an adsorption coefficient of 4,500 L/kg was measured(5).
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.
