Is ACN acetonitrile (CAS 75-05-8)?
Acetonitrile is physical properties manifest as a colorless, transparent liquid possessing a distinctive pungent odor. As a non-protonic solvent, acetonitrile exhibits exceptional solubility, dissolving various organic compounds, inorganic salts, and gaseous substances. It forms an infinitely miscible system with water, methanol, ethanol, and other alcohol-based solvents.
acetonitrile properties
Preparation of Acetonitrile
- It is produced as a byproduct of the acrylonitrile production process. It can also be made by hydrogenating carbon monoxide mixtures or dehydrating acetamide and ammonia.
- With the invention, a technique for producing high purity Acetonitrile from acetic acid and ammonia was revealed, which consists of two steps,
- Neutralizing acetic acid and ammonia to generate ammonium acetate,
- Mixing an aqueous solution of ammonium acetate and gaseous ammonia, preheating and putting the mixture into a fixed bed reactor filled with a catalyst aluminum oxide for reaction to generate acetonitrile with mixed gas, and after continuously refining the gas we got pure Acetonitrile.
Physical properties of Acetonitrile
- It has the appearance of a colorless, transparent liquid with a pleasant aroma.
- It's a low-density base with a density of 0.783 g/cm3.
- The melting point is -46 to -44 degrees Celsius, while the boiling temperature is 81.3 to 82.1°Celsius.
- In water, it is miscible.
Chemical properties of Acetonitrile
It's a nitrile (hydrogen cyanide) in which the hydrogen is replaced with a methyl group. It's also a polar molecule, which implies that its atoms may attract electrons to themselves. In addition, the nitrogen atom has a higher electronegative charge than the carbon atom.
