Acetonitrile? ??



In organic synthesis as starting material for acetophenone, alpha-naphthaleneacetic acid, thiamine, acetamidine. To remove tars, phenols, & coloring matter from petroleum hydrocarbons which are not soluble in acetonitrile. To extract fatty acids from fish liver oils & other animals & vegetable oils. Can be used to recrystallize steroids. As an indifferent medium in physicochemical investigations. Wherever a polar solvent having a rather high dielectric constant is required. As medium for promoting reactions involving ionization. As a solvent in non-aqueous titrations. As a nonaqueous solvent for inorganic salts.


Acetonitrile (methyl cyanide), CH3CN, is a colorless liquid with a sweet, ethereal odor. It is completely miscible with water and its high dielectric strength and dipole moment make it an excellent solvent for both inorganic and organic compounds including polymers.
