10.3 Possibility of hazardous reactions

A very dangerous fire hazard when exposed to heat, oxidizers or flame.The vapour is heavier than air and may travel along the ground; distant ignition possible.NITROMETHANE may explode if heated or strongly shocked, especially if mixed with acids, bases [Handling Chemicals Safely 1980. p. 687], acetone, aluminum powder, ammonium salts in the presence of organic solvents, haloforms (chloroform, bromoform), or hydrazine in methanol. Ignites on contact with alkyl aluminum or alkyl zinc halides. Reacts violently with strong bases (potassium hydroxide, calcium hydroxide), amines (1,2-diaminoethane, hydrazine), bromine, carbon disulfide, hydrocarbons, formaldehyde, metal oxides, lithium aluminum hydride, sodium hydride, strong oxidizing agents (lithium perchlorate, nitric acid, calcium hypochlorite). Reacts with aqueous silver nitrate to form explosive silver fulminate [Bretherick, 5th ed., 1995, p. 183]. Mixtures of nitromethane and aluminum chloride may explode when organic matter is present [Chem. Eng. News 26:2257. 1948]. Nitromethane, either alone or in a mixture with methanol and castor oil, has a delayed but violent reaction with powdered calcium hypochlorite [Haz. Home Chem 1963]. Nitromethane reacts violently with hexamethylbenzene [Lewis 2544]. Nitromethane is strongly sensitized by hydrazine [Forshey, D. RR. et al, Explosivestoffe, 1969, 17(6), 125-129].

12.Ecological information

12.1 Toxicity

  • Toxicity to fish: LC50; Species: Pimephales promelas (Fathead minnow); Conditions: static; Concentration: <278 mg/L for 96 hr
  • 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: When nitromethane was incubated with activated sludge, 36.2% mineralization occurred in 5 days(1,2). Degradation was low in a closed bottle biodegradability test, using a municipal sewage plant effluent innoculum, with 10% degradation occurring in 28 days(1,2). Aerobic C14 studies performed with soil microorganisms resulted in 5.1% conversion to CO2 in 35 days(1,2); during this time, 22.3% was lost as volatile products(1,2). Nitromethane present at 500 mg/L and inoculated with activated sludge from three municipal treatment plants was toxic to the microorganisms present over the 24 hour study period(3).

12.3 Bioaccumulative potential

A BCF value of 1.4 was measured for fish (Golden ide (Leuciscus idus melanotus)) in a static 3-day test with nitromethane present at 50 ppb(1,2). According to a classification scheme(3), this BCF value suggests that bioconcentration in aquatic organisms is low(SRC). Low bioconcentration was reported for tests using carp (Cyprinus carpio)(4), however actual BCF values were not reported(SRC). The bioconcentration factor in algae (Chorella fusca), as determined in a 24-hr experiment, was 960(1).

12.4 Mobility in soil

Using a structure estimation method based on molecular connectivity indices(1), the Koc of nitromethane can be estimated to be 10(SRC). According to a classification scheme(2), this estimated Koc value suggests that nitromethane is expected to have very high mobility in soil.

12.5 Other adverse effects

no data available

13.Disposal considerations

13.1 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.

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.
