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.
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 .

There’s currently no approved vaccine for norovirus, although Moderna has begun a phase three trial in the U.S. for a vaccine using mRNA technology and aims to test it in 25,000 adults worldwide.
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.
