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.

The following compounds are liquid at room temperature and are completely miscible with water; they are often used as solvents. Many of them are hygroscopic . Organic compounds
This Wikipedia page provides a comprehensive list of boiling and freezing points for various solvents.
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.
Water, being the most polar-solvent listed above, stabilizes the ionized species to a greater extent than does DMSO or Acetonitrile. Ionization - and, thus, acidity - would be greatest in water and lesser in DMSO and Acetonitrile, as seen in the table below, which shows p K a values at 25 °C for acetonitrile (ACN) [ 2 ] [ 3 ] [ 4 ] and ...
Two-time Grand Slam champion Simona Halep, working her way back from a drug suspension, and Hall of Famer Lleyton Hewitt's 16-year-old son Cruz were among the players awarded wild-card entries ...
About 6.7 million tonnes were produced worldwide in 2010, mainly for use as a solvent and for production of methyl methacrylate and bisphenol A, which are precursors to widely used plastics. [23] [24] It is a common building block in organic chemistry. It serves as a solvent in household products such as nail polish remover and paint thinner.
