colorless transparent liquid. It is miscible with water, diethyl ether, methanol, acetone, chloroform, carbon tetrachloride, vinyl chloride, methyl acetate, ethyl acetate, acetamide solution and many unsaturated hydrocarbons, and is not miscible with saturated hydrocarbons. Can dissolve some inorganic salts, such as silver nitrate, lithium nitrate and magnesium bromide. It can form an azeotropic mixture with water (water content 16%), and the azeotropic point is 76. Flammable, its vapor and air can form an explosive mixture, in the case of open flame, high heat or contact with the oxidant, there is a risk of combustion explosion. A strong reaction with an oxidizing agent can occur. With sulfuric acid, fuming sulfuric acid, chlorosulfonic acid, perchlorate reaction intense.
standard substance for chromatographic analysis. It can be used as a solvent for high pressure liquid chromatography (HPLC) and a stationary liquid for gas chromatography. Solvents for most inorganic compounds, spectrophotometric determination and non-aqueous titration solvents. Determination of carboxyl group as a diluent. Recrystallization of steroids, extraction of fatty acids, etc.
rats were orally administered with LD50:3800mg/kg. Keep away from fire, heat source, flammable and combustible materials, and prevent direct sunlight. Avoid mixing with oxidants, reductants, acids and alkalis. Warehouse temperature should not exceed 30 ℃.
