Material Safety Data Sheet (MSDS) - Acetonitrile - Pure Chemical
Acetonitrile, often abbreviated MeCN (methyl cyanide), is the chemical compound with the formula CH3CN and structure H3C−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). It is produced mainly as a … Meer weergeven 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 … Meer weergeven • Trichloroacetonitrile – a derivative of acetonitrile used to protect alcohol groups, and also used as a reagent in the Overman rearrangement Meer weergeven Acetonitrile is a byproduct from the manufacture of acrylonitrile. Most is combusted to support the intended process but an estimated several thousand … Meer weergeven Toxicity Acetonitrile has only modest toxicity in small doses.

Solubility exists on a spectrum. Substances may combine together poorly or very well, and it's … WebWhen acetonitrile and methanol are respectively mixed with water in the same ratio, the acetonitrile-based solution generally has a higher elution strength. In particular, in some cases where the mixture ratio is low, the same retention times can be achieved using acetonitrile with less than half the ratio of methanol, as can be seen for caffeine and … black sea regional map
