10.Stability and reactivity

10.1 Reactivity

no data available

10.2 Chemical stability

Stable under recommended storage conditions.

10.3 Possibility of hazardous reactions

Reacts with oxidizing agents . When air was admitted after vacuum evaporation of an ether peroxide solution, a violent explosion occurred. A halogenated aromatic nitro compound. Aromatic nitro compounds range from slight to strong oxidizing agents. If mixed with reducing agents, including hydrides, sulfides and nitrides, they may begin a vigorous reaction that culminates in a detonation. The aromatic nitro compounds may explode in the presence of a base such as sodium hydroxide or potassium hydroxide even in the presence of water or organic solvents. The explosive tendencies of aromatic nitro compounds are increased by the presence of multiple nitro groups.

10.4 Conditions to avoid

no data available

10.5 Incompatible materials

Solutions in ether may explode when evaporated.

10.6 Hazardous decomposition products

When heated to decomposition it emits toxic fumes of /nitrogen oxides/ & /fluorine/.

12.Ecological information

12.1 Toxicity

  • Toxicity to fish: no data available
  • Toxicity to daphnia and other aquatic invertebrates: no data available
  • Toxicity to algae: no data available
  • Toxicity to microorganisms: no data available

12.2 Persistence and degradability

AEROBIC: The half-life of 1-fluoro-2,4-dinitrobenzene in a dry silt loam soil was greater than 50 days(1) suggesting biodegradation occurs slowly in the environment(SRC).

12.3 Bioaccumulative potential

An estimated BCF of 7 was calculated in fish for 1-fluoro-2,4-dinitrobenzene(SRC), using an estimated log Kow of 1.83(1) and a regression-derived equation(1). According to a classification scheme(2), this BCF suggests the potential for bioconcentration in aquatic organisms is low.

12.4 Mobility in soil

Using a structure estimation method based on molecular connectivity indices(1), the Koc for 1-fluoro-2,4-dinitrobenzene can be estimated to be 575(SRC). According to a classification scheme(2), this estimated Koc value suggests that 1-fluoro-2,4-dinitrobenzene is expected to have low mobility in soil. It has been shown that nitrobenzenes adsorb strongly to clay surfaces and the mobility of 1-fluoro-2,4-dinitrobenzene is expected to be low in soils rich in clay content(3,4).

12.5 Other adverse effects

no data available

13.Disposal considerations

13.1 Disposal methods

Product

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.

Contaminated packaging

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.
