  malononitrile malononitrile 109-77-3 none 100%

  4.First-aid measures

  4.1 Description of necessary first-aid measures

  General advice

  Consult a physician. Show this safety data sheet to the doctor in attendance.

  If inhaled

  Fresh air, rest. Artificial respiration may be needed. Refer for medical attention. Half-upright position.

  In case of skin contact

  Remove contaminated clothes. Rinse and then wash skin with water and soap. Refer for medical attention .

  In case of eye contact

  First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.

  If swallowed

  Rinse mouth. Give a slurry of activated charcoal in water to drink. Induce vomiting (ONLY IN CONSCIOUS PERSONS!). Give one or two

  glasses of water to drink. Refer for medical attention .

  4.2 Most important symptoms/effects, acute and delayed

  Metabolized by body to cyanide and thiocyanate; effects of inhalation of toxic fumes will be related to cyanide. Causes brain and heart damage

  related to lack of cellular oxygen. It is classified as extremely toxic. Probable oral lethal dose for humans is 5-50 mg/kg, or between 7 drops and 1

  teaspoonful, for a 70 kg (150 lb.) person. (EPA, 1998)

  4.3 Indication of immediate medical attention and special treatment needed, if necessary

  Rapid support of respiration and circulation is essential to successful treatment of cyanide intoxication. Massive cyanide overdoses have survived

  with only good supportive care. Immediate attention should be directed toward assisted ventilation, administration of 100% oxygen, insertion of

  intravenous lines, and institution of cardiac monitoring. Obtain an arterial blood gas immediately and correct any severe metabolic acidosis (pH

  below 7.15). Oxygen (100%) should be used routinely in moderate or severely symptomatic patients even in the presence of a normal pO2, since

  100% O2 increases O2 delivery, may reactivate cyanide-inhibited mitochondrial enzymes, and potentiates the effect of thiosulfate. Avoid mouth to

  mouth resuscitation during CPR in order to prevent self poisoning. /Cyanides/

  5.Fire-fighting measures

  5.1 Extinguishing media

  Suitable extinguishing media

  To fight fire, use water, fog, spray, foam.

  5.2 Specific hazards arising from the chemical

  When heated to decomposition, malononitrile emits highly toxic fumes (cyanide). May polymerize violently on prolonged heating. Avoid heat.

  Hazardous polymerization may occur, at prolonged heating at 266F or contact with strong bases at lower temperatures. (EPA, 1998)

  5.3 Special protective actions for fire-fighters

  Wear self-contained breathing apparatus for firefighting if necessary.

  6.Accidental release measures

  6.1 Personal precautions, protective equipment and emergency procedures

  Use personal protective equipment. Avoid dust formation. Avoid breathing vapours, mist or gas. Ensure adequate ventilation. Evacuate personnel

  to safe areas. Avoid breathing dust. For personal protection see section 8.

  6.2 Environmental precautions

  Remove all ignition sources. Personal protection: chemical protection suit including self-contained breathing apparatus. Do NOT let this chemical

  enter the environment. Vacuum spilled material with specialist equipment. If appropriate, moisten first to prevent dusting.

  6.3 Methods and materials for containment and cleaning up

  Pick up and arrange disposal. Sweep up and shovel. Keep in suitable, closed containers for disposal.

  7.Handling and storage

  7.1 Precautions for safe handling

  Avoid contact with skin and eyes. Avoid formation of dust and aerosols. Avoid exposure - obtain special instructions before use.Provide

  appropriate exhaust ventilation at places where dust is formed. For precautions see section 2.2.

  7.2 Conditions for safe storage, including any incompatibilities

  Cool. Separated from strong bases and food and feedstuffs. Well closed. Keep in a well-ventilated room.

  Skin protection

  Wear impervious clothing. The type of protective equipment must be selected according to the concentration and amount of the dangerous

  substance at the specific workplace. 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

  polymerization on contact with strong bases (sodium hydroxide, potassium hydroxide) or when heated above 130° C. When stored at 70-80° C

  Toxicity to fish: LC50 Rainbow trout 1.6 mg/l/96 hr /Conditions of bioassay not specified

  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: Nitriles are biodegraded by enzyme-catalyzed hydrolysis to ultimately form carboxylic acids and ammonia(1,2). Thus, malononitrile

  may biodegrade in the environment(SRC).

  12.3 Bioaccumulative potential

  An estimated BCF of 3 was calculated for malononitrile(SRC), using a log Kow of -0.60(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

  The Koc of malononitrile is estimated as 11(SRC), using a measured log Kow of -0.60(1) and a regression-derived equation(2). According to a

  classification scheme(3), this estimated Koc value suggests that malononitrile is expected to have very high mobility in soil(SRC).

  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.
