Isopropyl Alcohol

 

2-propanol, the simplest secondary aliphatic alcohol, CH3CH(OH)CH3.

Isopropyl alcohol is a colorless liquid with a characteristic odor. Melting point, — 89.5°C; boiling point, 82.4°C; density, 0.7851 g/cm3 (20°C); flash point, 11.7°C; lower volume explosive limit in air, 2.5 percent by volume (25“C). Isopropyl alcohol is miscible in all proportions with water and organic solvents, with water forming an azeotrope (87.9 percent isopropyl alcohol; boiling point, 83.38°C). Isopropyl alcohol has all the properties of a secondary aliphatic alcohol.

Industrially, isopropanol is made by the direct or sulfuric-acid hydration of propylene. The raw material is the propane-propylene cut of cracked gas or the propylene fraction of petroleum pyrolysis. Isopropyl alcohol is used chiefly in making acetone (by dehydrogenation or incomplete oxidation), as a solvent (for example, of essential oils and resins), and as a component in antifreeze mixtures.
