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. isopropyl alcohol[¦ī·sə′prō·pəl ′al·kə‚hȯl] (organic chemistry) (CH3)2CHOH A colorless liquid that boils at 82.4°C; soluble in water, ether, and ethanol; used in manufacturing of acetone and its derivatives, of glycerol, and as a solvent.

alcohol [al´kah-hol] 1. any organic compound containing the hydroxy (-OH) functional group except those in which the OH group is attached to an aromatic ring, which are called phenols. Alcohols are classified as primary, secondary, or tertiary according to whether the carbon atom to which the OH group is attached is bonded to one, two, or three other carbon atoms and as monohydric, dihydric, or trihydric according to whether they contain one, two, or three OH groups; the latter two are called diols and triols, respectively.ethanol.2. an official preparation of ethanol, used as a disinfectant, solvent, and preservative, and applied topically as a rubbing compound, disinfectant, astringent, hemostatic, and coolant.absolute alcohol dehydrated a.benzyl alcohol a colorless liquid used as a bacteriostatic in solutions for injection and as a topical local anesthetic.dehydrated alcohol an extremely hygroscopic" >hygroscopic, transparent, colorless, volatile liquid used as a solvent and injected into nerves and ganglia for relief of pain.
