acetonitrile

CAS No. 75-05-8

Formula: C2H3N
Basic Info

Acetonitrile is the chemical compound with the formula CH 3CN. This colourless liquid is the simplest organic nitrile (hydrogen cyanide is a simpler nitrile, but the cyanide anion is not classed as organic). It is produced mainly as a byproduct of acrylonitrile manufacture. It is used as a polar aprotic solvent in organic synthesis and in the purification of butadiene.
In the laboratory, it is used as a medium-polarity solvent that is miscible with water and a range of organic solvents, but not saturated hydrocarbons. It has a convenient liquid range and a high dielectric constant of 38.8. With a dipole moment of 3.92D, acetonitrile dissolves a wide range of ionic and nonpolar compounds and is useful as a mobile phase in HPLC and LC-MS. The N-C-C skeleton is linear with a short C-N distance of 1.16 Å.
Acetonitrile was first prepared in 1847 by the French chemist Jean-Baptiste Dumas.

Immediate first aid: Ensure that adequate decontamination has been carried out. If patient is not breathing, start artificial respiration, preferably with a demand-valve resuscitator, bog-valve-mask device, or pocket mask, as trained. Perform CPR if necessary. Immediately flush contaminated eyes with gently flowing water. Do not induce vomiting. If vomiting occurs, lean patient forward or place on left side (head-down position, if possible) to maintain an open airway and prevent aspiration. Keep patient quiet and maintain normal body temperature. Obtain medical attention. /Cyanide and related compounds/

Carcinogenicity

Weight-of-Evidence Characterization Under the current Risk Assessment Guidelines (US EPA, 1987), ACN is assigned carcinogen class D, not classifiable as to human carcinogenicity. There is an absence of human evidence and the animal evidence is equivocal. Under the Proposed Guidelines for Carcinogen Risk Assessment (US EPA, 1996), the carcinogenic potential of ACN following inhalation, oral, or dermal exposure is best characterized as "cannot be determined because the existing evidence is composed of conflicting data (e.g., some evidence is suggestive of carcinogenic effects, but other equally pertinent evidence does not confirm any concern)." /Based on former classification guidelines/

Reproductive toxicity

No information is available on the reproductive or developmental effects of acetonitrile in humans. (1-3) Animal studies appear to suggest that acetonitrile may cause developmental and reproductive effects such as a decrease in average fetal body weight and a significant increase in the number of malformed offspring. (1-3)

12.1 Toxicity

  • Toxicity to fish: LC50; Species: Pimephales promelas (fathead minnow); Concentration: 1020 mg/L for 96 hr (hard water) /Conditions of bioassay not specified
  • Toxicity to daphnia and other aquatic invertebrates: LC50; Species: Daphnia magna (Water flea, age < or =24 hr); Conditions: freshwater, static, 20-22°C; Concentration: >10000 mg/L for 24 hr /formulated product
  • Toxicity to algae: EC50; Species: Pseudokirchneriella subcapitata (Green algae, exponential growth phase, 15000 cells/mL, UTEX 1648); Conditions: static, 24°C, dissolved oxygen 1-2 mg/L; Concentration: 5926 mg/L for 48 hr; Effect: physiology, decreased photosynthesis
  • Toxicity to microorganisms: no data available

12.2 Persistence and degradability

AEROBIC: Enzyme-catalyzed hydrolysis of nitriles, such as acetonitrile, has been shown to proceed by two distinct routes(1,2); a nitrilase transforms the nitriles directly into acids plus ammonium ion, or a nitrile hydratase forms the amide which is hydrolyzed to acid plus ammonium ion by amidase(1,2). A mixed microbial culture isolated from an environment contaminated with organic cyanides and PCBs utilized acetonitrile as the sole source of carbon and nitrogen(3). The mixed microbial culture was grown for 48 hrs at pH 7 with 1 g/L of acetonitrile; the final pH and ammonia concentration were determined to be 8.81 and 80.1 umol/mL, respectively(3). The biodegradation studies of acetonitrile with mixed cultures of microorganisms from activated sludge and sewage show that degradation proceeds sluggishly without acclimatization of microorganisms, particularly at high concentration(4,5). Degradation is faster with acclimatization(6-11). With activated sludge as microbial inoculum, the lag period of acetonitrile degradation was about 1 day after which the compound degraded with a half-life of 1.2 days(8). Acclimated mixed microbial cultures isolated by an enrichment culture technique degraded 58% acetonitrile in 5 days(9). The biodegradability of acetonitrile was also observed with river water; the 12 day ThOD (theoretical oxygen demand) with river water was 40%(10,11). Acclimation of the microorganisms was examined by redosing; the degradation was 5 times faster after acclimation; it was also 4 times faster at 20°C than at 5°C(10,11). The biodegradation is expected to be much slower in seawater than in freshwater(12). Acetonitrile, present at 100 mg/L, reached 65% of its theoretical BOD in 4 weeks using an activated sludge inoculum at 30 mg/L in the Japanese MITI test which classified the compound as readily biodegradable(13).

12.3 Bioaccumulative potential

An estimated BCF of 3 was calculated in fish for acetonitrile(SRC), using a log Kow of -0.34(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is low(SRC).

12.4 Mobility in soil

Acetonitrile has a reported measured Koc Value of 2.2(1). According to a classification scheme(2), this Koc value suggests that acetonitrile is expected to have very high mobility in soil(SRC).

12.5 Other adverse effects

no data available

13.Disposal considerations

    Handle in accordance with good industrial hygiene and safety practice. Wash hands before breaks and
    at the end of workday.
  Personal protective equipment
  Eye/face protection
    Face shield and safety glasses Use equipment for eye protection tested and approved under
    appropriate government standards such as NIOSH (US) or EN 166(EU).
  Skin protection
    Handle with gloves. Gloves must be inspected prior to use. Use proper glove removal technique
    (without touching glove's outer surface) to avoid skin contact with this product. Dispose of
    contaminated gloves after use in accordance with applicable laws and good laboratory practices.
    Wash and dry hands.
    The selected protective gloves have to satisfy the specifications of EU Directive 89/686/EEC and
    the standard EN 374 derived from it.
    Full contact
    Material: butyl-rubber
    Minimum layer thickness: 0,3 mm
    Break through time: 480 min

    If used in solution, or mixed with other substances, and under conditions which differ from EN 374,
    contact the supplier of the CE approved gloves. This recommendation is advisory only and must
    be evaluated by an industrial hygienist and safety officer familiar with the specific situation of
    anticipated use by our customers. It should not be construed as offering an approval for any
    specific use scenario.
  Body Protection
    Complete suit protecting against chemicals, Flame retardant antistatic protective clothing, The type
    of protective equipment must be selected according to the concentration and amount of the
    dangerous substance at the specific workplace.
  Respiratory protection
    Where risk assessment shows air-purifying respirators are appropriate use a full-face respirator
    with multi-purpose combination (US) or type ABEK (EN 14387) respirator cartridges as a backup
    to engineering controls. If the respirator is the sole means of protection, use a full-face supplied air
    respirator. Use respirators and components tested and approved under appropriate government
    standards such as NIOSH (US) or CEN (EU).
  Control of environmental exposure
    Prevent further leakage or spillage if safe to do so. Do not let product enter drains.
