Description

N-Methylaniline is an aniline derivative. It is an organic compound with the chemical formula C6H5NH(CH3). The substance exists as a colorless or slightly yellow viscous liquid and turns brown when exposed to air. The chemical is insoluble in water. It is used as a latent and coupling solvent and is also used as an intermediate for dyes, agrochemicals and other organic products manufacturing. N-Methylaniline is a principal component of MMA (monomethylaniline), an antiknock agent, used to increase the octane number, more effective than Methyl tert-butyl ether. Usually added to gasoline in concentrations around 1.3% mass.

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

The BOD of N-methylaniline in coarse-filtered Lake Superior harbor water over the course of 20 days was not sufficiently different from controls to calculate a degradation rate(1). Little BOD resulted when N-methylaniline was incubated at 21°C for 20 days in ground water, river water, or Lake Superior Harbor water(1). In a continuous biological treatment simulation test, complete DOC removal was achieved(3). N-Methylaniline (100 ppm) was moderately biodegradable in an activated sludge test with 42% total organic carbon removed(2). The test solution and acclimation procedure employed attempted to simulate industrial wastewater treated at the Fukashiba treatment plant in Japan. Aberrant behavior of N-methylaniline in a semi-continuous activated sludge (SCAS) biodegradation test was found to result from inadequate acclimation of the inoculum(4). It was degraded by Alcalignes sp. and Corynebacterium sp., both isolated from the activated sludge(4).

12.3 Bioaccumulative potential

N-Methylaniline was found to have very low bioconcentration in fish using the procedures of the Ministry of International Trade and Industry (MITI) in Japan(1,2). Using its log Kow of 1.66(3), one would estimate a BCF of 11 for N-methylaniline using a recommended regression equation(4). This would indicate that N-methylaniline would not bioconcentrate in aquatic organisms(SRC).

12.4 Mobility in soil

Since the pKa of N-methylaniline is 4.848(2), N-methylaniline will be partially ionized at acidic environmental pHs and its adsorption to soil would be expected to be pH-dependent(SRC). The Koc for N-methylaniline predicted from molecular structure is 65(3). According to a suggested classification scheme(5), this estimated Koc suggests that N- methylaniline will be highly mobile in soil(SRC). Batch equilibrium studies used to determine the adsorption isotherms for N-methylaniline to a Podzol (4.85% OC pH 2.8), an Alfisol (1.25% OC, pH 6.7) and a sediment (1.58% OC, pH 7.1) yielded the results (soil, Freundlich adsorption constants (Kf), Freundlich exponent (1/n), Koc): Podzol, 22.29, 0.89, 460; Alfisol, 0.59, 0.78, 47; Sediment, 1.12, 0.77, 71(1). N-Methylaniline will be almost completely ionized at the pH of the Podzol and therefore ionic interactions may be dominant(1,SRC). N-Methylaniline reacts slowly with humates possibly by adding to quinoidal structures in the humic substances(4). Covalent bond formation is inferred by the lack of extractability of the aniline from the humic material as well as reactions with model compounds(4).

12.5 Other adverse effects

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.
