often used as a solvent, with the chemical formula of CH₃CN. Also known as methyl cyanide, it is the simplest of the organic nitriles.

At normal temperatures, acetonitrile is a colorless liquid. Its molecular weight is 41.05, with a melting temperature of -45C and a boiling temperature of 81.6C. The four main producers of acetonitrile in the United States are: BP Chemicals , Dupont, J.T. Baker Chemical , and Sterling Chemicals . In 1992, 32.3 million pounds (14,700 t) of acetonitrile were produced in the U.S.

Its primary use is as an extraction solvent for butadiene. It is also used as a chemical intermediate in pesticide manufacturing, and as a general solvent for many compounds. It is also used as a starting material for producing compounds like acetophenone, thiamine, etc. Finally, it can be used in the production of acrylic fiber s, perfumes, nitrile rubber , and ABS resin s. Trends for acetonitrile generally follow those of acrylonitrile.

Acetonitrile is absorbed through oral, dermal, or inhalation exposure. It is metabolizedMetabolism in the most general sense, is the ingestion and breakdown of complex compounds, coupled with the liberation of energy, and the consequent generation of waste products. It is major process of living organisms, and because this process can happen into hydrogen cyanideProperties General Name Hydrogen cyanide Chemical formula H CN Appearance Colourless liquid Physical Formula weight 27. 0 amu Melting point 260 K (-13 °C) Boiling point 299 K (26 °C) Density 0. 7 ×103 kg/ m3 Solubility very soluble Thermochemistry Δ and thiocyanateThiocyanate (also known as sulphocyanate is a functional group consisting of sulfur, carbon, and nitrogen: :S C N- It has a charge of 1-. It is analogous to the cyanate ion, with oxygen replaced by sulfur. It was formerly known as rhodanide (from a Greek, which is a serious cause of health problems in humanHuman beings are defined variously in biological, spiritual, and cultural terms, or in combinations thereof. Biologically, they are classified as Homo sapiens ( Latin for knowing man , a primate species of mammal with a highly developed brain. In spirituas. Acetonitrile liquid or vaporVapor ( US English) or vapour ( British English) is the gaseous state of matter. Although vapor and gas are frequently used interchangeably, vapor often carries the connotation of gaseous matter in a state of equilibrium with identical matter in a liquid is an acute irritant, irritating the skin, eyes, and respiratory tract. At high doses, death can occur due to respiratory failureRespiratory failure is a medical term for inadequate gas exchange by the respiratory system. Common causes include pneumonia, chronic obstructive airway disease (caused by tobacco smoking), or drug overdose. Emergency treatment follows the principles of c. Lower doses have symptomThe term symptom has two similar meanings in the context of physical and mental health: A symptom can be a physical condition which shows that one has a particular illness or disorder (see e. Longman, 1995). An example of a symptom in this sense of the wos similar to those of cyanideA cyanide is any chemical compound that contains the group C≡N, with the carbon atom triple bonded to the nitrogen atom. Inorganic cyanides contain the highly toxic cyanide ion C N- and are the salts of the acid hydrogen cyanide ( HCN). Organic cyan poisoning, including salivation, nausea, unconsiousness, convulsions, etc. Prolonged exposure to acetonitrile has possible symptoms, including anorexia, headaches, and other related symptoms. There is no information (currently) about the possibility of acetonitrile's carcinogenicity.
