Product Name：Acetonitrile Molecular format：C2H3N CAS No：75-05-8 Product molecular structure：   Chemical Properties:： Colorless transparent liquid. It is miscible with water, ether, methanol, acetone, chloroform, carbon tetrachloride, ethylene chloride, methyl acetate, ethyl acetate, acetamide solution and many unsaturated hydrocarbons, but not with saturated hydrocarbons. It can dissolve some inorganic salts, such as silver nitrate, lithium nitrate and magnesium bromide. It can form an azeotropic mixture with water (containing 16% water), with a azeotropic point of 76 ℃. Flammable, its vapor and air can form an explosive mixture, which may cause combustion and explosion in case of open fire, high heat or contact with oxidant. It can react strongly with oxidant. It reacts violently with sulfuric acid, oleum, chlorosulfonic acid, perchlorate, etc.   Application： Acetonitrile Chromatographic analysis of reference materials. It can be used as solvent and stationary liquid of high pressure liquid chromatography (HPLC). Solvents for most inorganic compounds, spectrophotometric and non-aqueous titration solvents. It is used as diluent when determining carboxyl group. Recrystallization of steroids, extraction of fatty acids, etc.
