Characteristics of Acetonitrile
1.Acetonitrile is a colorless liquid. It is completely misciblewith water and alcohol. Its high dipole moment makes it anexcellent solvent for many organic compounds as wellas someinorganic compounds.
2.Acetonitrile is chemically stable and is a strong solvent. Itis mainly used for the synthesis of organic compounds, and issuitable for electrical-chemical reaction and nonaqueous titration.Acetonitrile easily solvates with cations and enhances thereactivity of anions.
3.As with other nitrile compounds, the reactivity ofacetonitrile''s cyano group enables the production of manynitrogen-containing organic intermediates.
