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.

Acetone (2-propanone or dimethyl ketone) is an organic compound with the formula (CH 3) 2 CO. [22] It is the simplest and smallest ketone (>C=O).It is a colorless, highly volatile, and flammable liquid with a characteristic pungent odour, very reminiscent of the smell of pear drops.
Tetrakis(acetonitrile)copper(I) tetrafluoroborate forms colorless crystals in the orthorhombic crystal system in the space group Pna21 with the lattice parameters a = 23.882 Å; b = 8.3285 Å; c = 20.338 Å, and twelve unit cells.

The anion [Ce(NO 3) 6] 2− has T h (idealized O h) molecular symmetry. The CeO 12 core defines an icosahedron. [4] Ce 4+ is a strong one-electron oxidizing agent. In terms of its redox potential (E° ≈ 1.61 V vs. N.H.E.) it is an even stronger oxidizing agent than Cl 2 (E° ≈ 1.36 V). Few shelf-stable reagents are stronger oxidants.
Trichloroacetonitrile can be obtained by chlorination of acetonitrile on a zinc, copper and alkaline earth metal halide-impregnated activated carbon catalyst at 200–400 °C with a 54% yield. [ 3 ] The high temperatures required by this process favours the formation of byproducts, such as tetrachloromethane .
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.
