About AcetonitrileOccurrence
The emission lines of acetonitrile were detected by radio telescope in the nucleus of comet C/1973 E1 (Kohoutek) on December 1, 1973. Astronomers at ESO, with the help of the ALMA telescope, detected larger amounts of acetonitrile around the young star MWC 480 for the first time in April 2015.
Production
Possibilities for production are nucleophilic substitution reactions of e.g. bromomethane with sodium cyanide (NaCN). Industrially, acetonitrile is produced in relatively small quantities as a by-product in the manufacture of acrylonitrile. Price and availability are therefore linked to the production of polyacrylonitrile.
Properties
When heated to high temperatures and in the event of fire, acetonitrile gives off toxic gases such as hydrogen cyanide and nitrogen oxides. Explosive mixtures are formed with air. Acetonitrile attacks rubber and dissolves many polymers. When in contact with sulfuric acid under heat, explosive polymerization may occur. Acetonitrile forms with water an azeotropic mixture of 83.7 wt.% acetonitrile to 16.3 wt.% water and a boiling point of 76.5 °C, 5.5 K below the boiling point of pure acetonitrile.
Safety characteristics
Acetonitrile forms highly flammable vapor-air mixtures. The compound has a flash point at 2 °C. The explosion range is between 3.0% by volume (50 g/m3) as the lower explosion limit (LEL) and 17% by volume as the upper explosion limit (UEL). The limiting oxygen concentration is 12.7 vol% at 25 °C. The limiting gap width was determined to be 1.5 mm. This results in an assignment to explosion group IIA. The ignition temperature is 525 °C. The substance thus is assigned into temperature class T1. The electrical conductivity is rather low at 6-10-8 S-m-1.
Use
Acetonitrile is a common solvent in the laboratory, in chemical analysis (e.g. HPLC) and in technical chemistry, mainly for the extraction of 1,3-butadiene. Acetonitrile is used as a solvent for conducting salts in double-layer capacitors.
Acetonitrile-d3
Fully deuterated acetonitrile (acetonitrile-d3) - in which all three hydrogen atoms have been replaced by deuterium - is used as a solvent in NMR spectroscopy.
Safety information
Acetonitrile is an irritant. It is harmful by inhalation, ingestion and skin contact. Acetonitrile is absorbed through the skin (percutaneously) and acts as a blood poison in the body. Acetonitrile exhibits low toxicity at low doses. It is metabolized to hydrogen cyanide, which is the cause of the observed symptoms. Symptoms are usually delayed (between 2 and 12 hours) because it takes some time for the body to metabolize acetonitrile to cyanide. Cases of poisoning by inhalation, oral ingestion, or skin absorption in humans are rare but not unknown. Symptoms that do not appear until several hours after exposure include difficulty breathing, low pulse, nausea, and nausea. In serious cases, convulsions and coma may occur, followed by death from respiratory failure. Countermeasures are as for cyanide poisoning.
