WebAcetonitrile (CH 3 CN), CAS 75-05-8, also known as methyl cyanide or cyanomethane, is the simplest organic nitrile. Produced mainly as a byproduct of manufacturing acrylonitrile, acetonitrile is a colorless liquid with an ether-like odor. Available in various grades, acetonitrile is commonly used in the laboratory: WebAcetonitrile is the organic eluant of choice for peptide separations, while isopropanol, ethanol, and methanol are used to a lesser extent. It is desirable to make the starting …
WebNext, acrylonitrile was made by feeding acrolein, ammonia and air over the catalyst that produced acrylic acid from acrolein. This success suggested that acrylonitrile might be made directly from propylene by carrying out the entire reaction in a single step with bismuth phosphomolybdate. WebMethanol and acetonitrile are organic acids commonly used as the mobile phase in reverse-phase chromatography. The properties of these two organic acids differ, and below we outline 7 key differences to keep in mind when using methanol or acetonitrile for analysis. 1, Column Pressure. 2, Absorption Spectrum.
