Acetonitrile is used mainly as a solvent in the purification of butadiene in refineries. Specifically, acetonitrile is fed into the top of a distillation column filled with hydrocarbons including butadiene, and as the acetonitrile falls down through the column, it absorbs the butadiene which is then sent from the bottom of the tower to a second separating tower.

Tetrakis(acetonitrile)copper(I) tetrafluoroborate can be prepared starting from nitrosyl tetrafluoroborate, which is obtained from dinitrogen tetroxide and tetrafluoroboric acid. The nitrosyl salt is then reacted with metallic copper in acetonitrile , initially producing a green-blue copper(II) complex.
It is highly soluble in polar organic solvents such as acetone and acetonitrile. The salt consists of a positively charged tetrabutylammonium, a quaternary ammonia cation and a weakly basic hexafluorophosphate anion. These species are chemically inert, which allows the salt to serve as an inert electrolyte over a wide potential range.
A colorless liquid, it is derived from acetonitrile (CH 3 CN) by replacement of one H with Cl. In practice, it is produced by dehydration of chloroacetamide. [1] The compound is an alkylating agent, [2] and as such is handled cautiously. Chloroacetonitrile is also generated in situ by the reaction of acetonitrile with sulfur monochloride.
The acetonitrile ligands protect the Cu + ion from oxidation to Cu 2+, but are rather poorly bound: with other counterions, the complex forms di-[1] and tri-acetonitrilo [6] complexes and is also a useful source of unbound Cu(I). [5] Water-immiscible organic nitriles have been shown to selectively extract Cu(I) from aqueous chloride solutions. [7]

In contrast, the chlorination of acetonitrile saturated with hydrogen chloride leads to pure trichloroacetonitrile even at 50–80 °C in good yields. [ 4 ] Like other halogenated acetonitriles, trichloroacetonitrile is produced from organic substances such as algae , humic acids and proteinaceous material in the disinfecting chlorination of ...
