10.3 Possibility of hazardous reactions

ACETANILIDE is an amide. Flammable gases are formed by the reaction of organic amides with strong reducing agents. Amides are very weak bases (weaker than water). Imides are less basic yet and in fact react with strong bases to form salts. That is, they can react as acids. Mixing amides with dehydrating agents such as P2O5 or SOCl2 generates the corresponding nitrile. The combustion of these compounds generates mixed oxides of nitrogen (NOx).

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

Several tests indicate that acetanilide biodegrades rapidly under aerobic conditions(1-3). One screening test, based on COD measurements, using an activated sludge seed and an initial chemical concentration of 200 ppm, reported a 94% COD removal after 5 days(1). A screening test using an acclimated riverwater seed, based on BOD measurements, reported an 80% BODT after 8 days(2). A grab sample test from the Nile River, using an initial chemical concentration of 6-7 ppm, reported 100% degradation after 43 days incubation(3).

12.3 Bioaccumulative potential

An estimated BCF value of 4.5 was calculated for acetanilide(SRC), using an experimental log Kow of 1.16(1,SRC) and a recommended regression-derived equation(2). According to a classification scheme(3), this BCF value suggests that bioconcentration in aquatic organisms is low(SRC).

12.4 Mobility in soil

The Koc of acetanilide is estimated as approximately 38(SRC), using an experimental log Kow of 1.16(1,SRC) and a regression-derived equation(2,SRC). A Koc of 27 was experimentally determined for acetanilide, using silt loam and sandy loam, with % organic matter ranging from 1.09-5.92 (Kom was converted to Koc by multiplying by 1.724), and pH ranging from 5.9-7.5(4). According to a recommended classification scheme(3), the estimated and measured Koc values suggest that acetanilide has very high mobility in soil(SRC).

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.
