Acetonitrile, often abbreviated MeCN (methyl cyanide), is the chemical compound with the formula CH 3 CN and structure H 3 C−C≡N. This colourless liquid is the simplest organic nitrile ( hydrogen cyanide is a simpler nitrile, but the cyanide anion is not classed as organic ).
Fisher Scientific Company issued its first public stock in 1965, and that year the company had $58 million in sales and close to a million customer transactions. In 1968 Fisher shares were listed on the New York Stock Exchange. [2] In 1965 the company introduced the Differential Thermalyzer, a differential thermal analysis instrument. [3]
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.
Bis(acetonitrile)palladium dichloride is the coordination complex with the formula PdCl 2 (NCCH 3) 2. It is the adduct of two acetonitrile ligands with palladium(II) chloride. It is a yellow-brown solid that is soluble in organic solvents. The compound is a reagent and a catalyst for reactions that require soluble Pd(II). [1]
The aqueous solution consists of acrylonitrile, acetonitrile, hydrocyanic acid, and ammonium sulfate (from excess ammonia). A recovery column removes bulk water, and acrylonitrile and acetonitrile are separated by distillation. One of the first useful catalysts was bismuth phosphomolybdate (Bi 9 PMo 12 O 52) supported on silica. [11]
