Applications

Acetonitrile is utilized as a polar aprotic solvent in organic synthesis, and in the purification of butadiene. It is used in all the analytical laboratories as a major component of mobile phase in High Performance Liquid Chromatography (HPLC) and in Liquid Chromatography - Mass Spectrometry (LC-MS). It is used for the extraction of fatty acids, spinning fibers and casting and molding of plastic materials. Aqueous two-phase systems based on acetonitrile and carbohydrates play an important character in the extraction and purification of biomolecules called vanillins. It acts as a stabilizer for the chlorinated solvents, and finds use in the production of DNA oligonucleotides.

Notes

Incompatible with alkali metals, acids, bases, reducing agents and oxidizing agents. Highly flammable. Store it away from heat, sparks, and flame exposure.

Literature References

Polar aprotic solvent for a wide variety of reactions, including nucleophilic substitutions, oxidations, reductions and organometallic reactions. Widely used with crown ethers for the generation of 'naked' anions from their salts; see, e.g. 18-Crown-6, A11249 . Preferred solvent for RuO4 oxidations, due to its coordinating ability; see Ruthenium(III)­ chloride hydrate, 11043 .

Undergoes the Ritter reaction with alcohols or olefins in the presence of acid to give N-substituted acetamides. For benzylic alcohols, modified conditions employing boron trifluoride etherate give high yields: Synth. Commun., 24, 601 (1994). For an example, see 4-Methyl­benzyl­ alcohol, A15315 .

For use in the mild conversion of amides to nitriles, see Benzamide, A10501 .
