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.

Treatment-emergent central sleep apnea (TECSA), also known as complex sleep apnea, is a type of sleep apnea that typically develops when a patient starts CPAP therapy for OSA. This can occur when ...
The structure of a nitrile: the functional group is highlighted blue. In organic chemistry, a nitrile is any organic compound that has a −C≡N functional group.The name of the compound is composed of a base, which includes the carbon of the −C≡N, suffixed with "nitrile", so for example CH 3 CH 2 C≡N is called "propionitrile" (or propanenitrile).

A substance intended for use in the diagnosis, cure, mitigation, treatment, or prevention of disease. A substance recognized by an official pharmacopeia or formulary . Biological products are included within this definition and are generally covered by the same laws and regulations, but differences exist regarding their manufacturing processes ...
Other symptoms: Ant bites are typically painful and itchy. In addition to the bites, fire ants use their stinger to inject a venom called solenopsin, which causes a burning sensation, Frye says.
