Basic information of acetonitrile

Views: 1     Author: Site Editor     Publish Time: 2022-07-25      Origin: Site

Acetonitrile is an organic compound with the chemical formula CH3CN or c2h3n. It is a colorless transparent liquid with excellent solvent performance. It can dissolve a variety of organic, inorganic and gaseous substances, and is infinitely miscible with water and alcohol. Acetonitrile is an important organic intermediate, which can undergo typical nitrile reactions and is used to prepare many typical nitrogen-containing compounds.
