Properties:
Isopropanol is also known as isopropyl alcohol. It is the simplest secondary alcohol and is one of the isomers of n-propanol. It is a kind of flammable liquid which is colorless with strong smell being similar to the smell of the mixture of ethanol and acetone. It is soluble in water, alcohol, ether, benzene, chloroform and most organic solvents and is miscible with water, alcohol, ether and can form azeotrope with water. Density (specific gravity): 0.7863g/cm3, melting point:-88.5 ℃, boiling point: 82.5 ℃, flash point: 11.7 ℃, ignition point: 460 ℃, refractive index: 1.3772. Its vapor can cause slight irritation on the eyes, nose and throat; it can be absorbed through the skin. Its vapor can form explosive mixture with air. Its explosion limit is 2.0% to 12% (by volume). It belongs to a moderate explosive hazardous material and flammable, low toxic substance. The toxicity of its vapors is twice as high as ethanol while oral administration causes the opposite toxicity.
Application:
Isopropyl alcohol is an important chemical products and raw materials. It is mainly applied to various fields including pharmaceutical, cosmetics, plastics, fragrances, paint as well as being used as the dehydrating agent and cleaning agent in and electronics industry. It can also be used as the reagent for determination of barium, calcium, magnesium, nickel, potassium, sodium and strontium. It can also be used as the reference material of chromatographic analysis.
Package and Storage:
Typically packaged in 200-liter drums or ISO tanks.
Store in a cool, well-ventilated area.
